NavPix is the proprietary name applied by Navman to its technology that combines an image with geographical data.
113-415: The "NavPix" name is used for both the software and the geo-referenced image that results from that software. The NavPix technology enables users to take a JPEG image using the integrated digital camera on the N Series ("N" for NavPix), iCN 720 or iCN 750 portable Navman GPS navigation devices. The Navman's GPS ( Global Positioning System ) receiver determines the latitude and longitude of where that image
226-451: A lossless graphics format such as TIFF , GIF , PNG , or a raw image format . The JPEG standard includes a lossless coding mode, but that mode is not supported in most products. As the typical use of JPEG is a lossy compression method, which reduces the image fidelity, it is inappropriate for exact reproduction of imaging data (such as some scientific and medical imaging applications and certain technical image processing work). JPEG
339-539: A manuscript to a publisher, is divided into two distinct phases: peer review and production. The process of peer review is organized by the journal editor and is complete when the content of the article, together with any associated images, data, and supplementary material are accepted for publication. The peer review process is increasingly managed online, through the use of proprietary systems, commercial software packages, or open source and free software. A manuscript undergoes one or more rounds of review; after each round,

In the early 21st century, this process was streamlined by the introduction of e-annotations in Microsoft Word , Adobe Acrobat , and other programs, but it still remained a time-consuming and error-prone process. The full automation of the proof correction cycles has only become possible with the onset of online collaborative writing platforms, such as Authorea , Google Docs , Overleaf , and various others, where

Some journals, particularly newer ones, are now published in electronic form only . Paper journals are now generally made available in electronic form as well, both to individual subscribers, and to libraries. Almost always these electronic versions are available to subscribers immediately upon publication of
678-468: A JPEG of cover art in the ID3v2 tag. Many JPEG files embed an ICC color profile ( color space ). Commonly used color profiles include sRGB and Adobe RGB . Because these color spaces use a non-linear transformation, the dynamic range of an 8-bit JPEG file is about 11 stops ; see gamma curve . If the image doesn't specify color profile information ( untagged ), the color space is assumed to be sRGB for
791-404: A block boundary for all channels (because the edge would end up on top or left, where – as aforementioned – a block boundary is obligatory). Rotations where the image is not a multiple of 8 or 16, which value depends upon the chroma subsampling, are not lossless. Rotating such an image causes the blocks to be recomputed which results in loss of quality. When using lossless cropping, if

The Journal des sçavans (later spelled Journal des savants ), established by Denis de Sallo , was the earliest academic journal published in Europe. Its content included obituaries of famous men, church history, and legal reports. The first issue appeared as

Some critics complain that this de facto system has emerged without thought to its consequences; they claim that the predictable result is the publication of much shoddy work, as well as unreasonable demands on the already limited research time of young scholars. To make matters worse, the circulation of many humanities journals in

That lawsuit was filed by Zappos.com , Inc., which was allegedly threatened by Global Patent Holdings, and sought a judicial declaration that the '341 patent is invalid and not infringed. Global Patent Holdings had also used the '341 patent to sue or threaten outspoken critics of broad software patents, including Gregory Aharonian and

It also remains unclear whether this is practical in fields outside the sciences, where there is much less availability of outside funding. In 2006, several funding agencies , including the Wellcome Trust and several divisions of the Research Councils in

The other articles in such hybrid journals are either made available after a delay or remain available only by subscription. Most traditional publishers (including Wiley-Blackwell , Oxford University Press , and Springer Science+Business Media ) have already introduced such

This mathematical operation converts each frame/field of the video source from the spatial (2D) domain into the frequency domain (a.k.a. transform domain). A perceptual model based loosely on the human psychovisual system discards high-frequency information, i.e. sharp transitions in intensity, and color hue. In the transform domain,

Available data indicate that these companies have profit margins of around 40% making it one of the most profitable industries, especially compared to the smaller publishers, which likely operate with low margins. These factors have contributed to the " serials crisis " – total expenditures on serials increased 7.6% per year from 1986 to 2005, yet

However, this method did not work well. Robert K. Merton , a sociologist, found that 92% of cases of simultaneous discovery in the 17th century ended in dispute. The number of disputes dropped to 72% in the 18th century, 59% by
1921-425: A paper is an academic work that is usually published in an academic journal . It contains original research results or reviews existing results. Such a paper, also called an article, will only be considered valid if it undergoes a process of peer review by one or more referees (who are academics in the same field) who check that the content of the paper is suitable for publication in the journal. A paper may undergo

At the end of this process, a final version of record is published. From time to time some published journal articles have been retracted for different reasons, including research misconduct. Academic authors cite sources they have used, in order to support their assertions and arguments and to help readers find more information on
2147-448: A series of reviews, revisions, and re-submissions before finally being accepted or rejected for publication. This process typically takes several months. Next, there is often a delay of many months (or in some fields, over a year) before an accepted manuscript appears. This is particularly true for the most popular journals where the number of accepted articles often outnumbers the space for printing. Due to this, many academics self-archive
2260-521: A slow connection, allowing a reasonable preview after receiving only a portion of the data. However, support for progressive JPEGs is not universal. When progressive JPEGs are received by programs that do not support them (such as versions of Internet Explorer before Windows 7 ) the software displays the image only after it has been completely downloaded. There are also many medical imaging, traffic and camera applications that create and process 12-bit JPEG images both grayscale and color. 12-bit JPEG format
2373-528: A twelve-page quarto pamphlet on Monday, 5 January 1665, shortly before the first appearance of the Philosophical Transactions of the Royal Society , on 6 March 1665. The publishing of academic journals has started in the 17th century, and expanded greatly in the 19th. At that time, the act of publishing academic inquiry was controversial and widely ridiculed. It was not at all unusual for

JPEG files usually have a filename extension of "jpg" or "jpeg". JPEG/JFIF supports a maximum image size of 65,535×65,535 pixels, hence up to 4 gigapixels for an aspect ratio of 1:1. In 2000, the JPEG group introduced a format intended to be a successor, JPEG 2000 , but it
2599-558: Is a central concept for most academic publishing; other scholars in a field must find a work sufficiently high in quality for it to merit publication. A secondary benefit of the process is an indirect guard against plagiarism since reviewers are usually familiar with the sources consulted by the author(s). The origins of routine peer review for submissions dates to 1752 when the Royal Society of London took over official responsibility for Philosophical Transactions. However, there were some earlier examples. While journal editors largely agree

The overall number of journals contained in the WOS database increased from around 8,500 in 2010 to around 9,400 in 2020, while the number of articles published increased from around 1.1 million in 2010 to 1.8 million in 2020. Most scientific research

This minimal format does not include any of the advanced features found in the TIFF JPEG specification or any application specific file format. Nor should it, for the only purpose of this simplified format is to allow the exchange of JPEG compressed images. Image files that employ JPEG compression are commonly called "JPEG files", and are stored in variants of
2938-432: Is also a tendency for existing journals to divide into specialized sections as the field itself becomes more specialized. Along with the variation in review and publication procedures, the kinds of publications that are accepted as contributions to knowledge or research differ greatly among fields and subfields. In the sciences, the desire for statistically significant results leads to publication bias . Academic publishing
3051-434: Is also considered that "Online scientific interaction outside the traditional journal space is becoming more and more important to academic communication". In addition, experts have suggested measures to make the publication process more efficient in disseminating new and important findings by evaluating the worthiness of publication on the basis of the significance and novelty of the research finding. In academic publishing,

American Psychological Association journals' rejection rates ranged "from a low of 35 per cent to a high of 85 per cent." The complement is called "acceptance rate". The process of academic publishing, which begins when authors submit

3616-507: Is critically important, humanities publications often take years to write and years more to publish. Unlike the sciences, research is most often an individual process and is seldom supported by large grants. Journals rarely make profits and are typically run by university departments. The following describes the situation in the United States. In many fields, such as literature and history, several published articles are typically required for

An equally prestigious site of publication within U.S. computer science are some academic conferences . Reasons for this departure include a large number of such conferences, the quick pace of research progress, and computer science professional society support for the distribution and archiving of conference proceedings . Since 2022,

Several alterations to a JPEG image can be performed losslessly (that is, without recompression and the associated quality loss) as long as the image size is a multiple of 1 MCU block (Minimum Coded Unit) (usually 16 pixels in both directions, for 4:2:0 chroma subsampling ). Utilities that implement this include: Blocks can be rotated in 90-degree increments, flipped in

The patent was under reexamination by the U.S. Patent and Trademark Office from 2000 to 2007; in July 2007, the Patent Office revoked all of the original claims of the patent but found that an additional claim proposed by Global Patent Holdings (claim 17)
4068-680: Is initially published in scientific journals and considered to be a primary source . Technical reports , for minor research results and engineering and design work (including computer software), round out the primary literature. Secondary sources in the sciences include articles in review journals (which provide a synthesis of research articles on a topic to highlight advances and new lines of research), and books for large projects, broad arguments, or compilations of articles. Tertiary sources might include encyclopedias and similar works intended for broad public consumption or academic libraries. A partial exception to scientific publication practices

There is also an interlaced progressive JPEG format, in which data is compressed in multiple passes of progressively higher detail. This is ideal for large images that will be displayed while downloading over

Both open and closed journals are sometimes funded by the author paying an article processing charge , thereby shifting some fees from the reader to the researcher or their funder. Many open or closed journals fund their operations without such fees and others use them in predatory publishing . The Internet has facilitated open access self-archiving , in which authors themselves make

The part of academic written output that is not formally published but merely printed up or posted on the Internet is often called " grey literature ". Most scientific and scholarly journals, and many academic and scholarly books, though not all, are based on some form of peer review or editorial refereeing to qualify texts for publication. Peer review quality and selectivity standards vary greatly from journal to journal, publisher to publisher, and field to field. Most established academic disciplines have their own journals and other outlets for publication, although many academic journals are somewhat interdisciplinary , and publish work from several distinct fields or subfields.

However, the United States' output dropped from 52.3% to 49.4% of the world's total, and its portion of the top one percent dropped from 65.6% to 62.8%. Iran, China, India , Brazil , and South Africa were the only developing countries among

The arrival of online publishing opportunities has radically transformed the economics of the field and the shape of the future is controversial. Unlike science, where timeliness
5311-473: The 1990s declined to almost untenable levels, as many libraries cancelled subscriptions, leaving fewer and fewer peer-reviewed outlets for publication; and many humanities professors' first books sell only a few hundred copies, which often does not pay for the cost of their printing. Some scholars have called for a publication subvention of a few thousand dollars to be associated with each graduate student fellowship or new tenure-track hire, in order to alleviate

Meanwhile, monographs are increasingly expected for tenure in the humanities. In 2002 the Modern Language Association expressed hope that electronic publishing would solve the issue. In 2009 and 2010, surveys and reports found that libraries faced continuing budget cuts, with one survey in 2009 finding that 36% of UK libraries had their budgets cut by 10% or more, compared to 29% with increased budgets.

Some fields, like economics, may have very "hard" or highly quantitative standards for publication, much like the natural sciences. Others, like anthropology or sociology, emphasize field work and reporting on first-hand observation as well as quantitative work. Some social science fields, such as public health or demography , have significant shared interests with professions like law and medicine , and scholars in these fields often also publish in professional magazines .

Most image capture devices (such as digital cameras) that output JPEG are actually creating files in the Exif format, the format that the camera industry has standardized on for metadata interchange. On the other hand, since the Exif standard does not allow color profiles, most image editing software stores JPEG in JFIF format, and includes the APP1 segment from the Exif file to include

The patent was originally owned and assigned to General Electric. The patent expired in December 2007, but Princeton has sued large numbers of companies for "past infringement" of this patent. (Under U.S. patent laws, a patent owner can sue for "past infringement" up to six years before

The JPEG committee has as one of its explicit goals that their standards (in particular their baseline methods) be implementable without payment of license fees, and they have secured appropriate license rights for their JPEG 2000 standard from over 20 large organizations. Beginning in August 2007, another company, Global Patent Holdings, LLC claimed that its patent ( U.S. patent 5,253,341 ) issued in 1993,

On March 5, 2008, the U.S. Patent and Trademark Office agreed to reexamine the '341 patent, finding that the new prior art raised substantial new questions regarding
6780-454: The apparent crisis has to do with the combined pressure of budget cuts at universities and increased costs for journals (the serials crisis ). The university budget cuts have reduced library budgets and reduced subsidies to university-affiliated publishers. The humanities have been particularly affected by the pressure on university publishers, which are less able to publish monographs when libraries can not afford to purchase them. For example,

Although, similar desire is also present in the subscription model, where publishers increase numbers or published articles in order to justify raising their fees. It may be criticized on financial grounds as well because the necessary publication or subscription fees have proven to be higher than originally expected. Open access advocates generally reply that because open access

Beginning in 2011 and continuing as of early 2013, an entity known as Princeton Digital Image Corporation, based in Eastern Texas, began suing large numbers of companies for alleged infringement of U.S. patent 4,813,056 . Princeton claims that
8588-575: The first edition was published in June 2009. In 2002, Forgent Networks asserted that it owned and would enforce patent rights on the JPEG technology, arising from a patent that had been filed on October 27, 1986, and granted on October 6, 1987: U.S. patent 4,698,672 by Compression Labs ' Wen-Hsiung Chen and Daniel J. Klenke. While Forgent did not own Compression Labs at the time, Chen later sold Compression Labs to Forgent, before Chen went on to work for Cisco . This led to Forgent acquiring ownership over
8701-432: The following Exif segment, being less strict about requiring it to appear first. The most common filename extensions for files employing JPEG compression are .jpg and .jpeg , though .jpe , .jfif and .jif are also used. It is also possible for JPEG data to be embedded in other file types – TIFF encoded files often embed a JPEG image as a thumbnail of the main image; and MP3 files can contain
8814-481: The geographical information is written to the meta data, the image itself can be shared between compatible devices or uploaded to Navman's NavPix Library which offers a wide range of NavPix images that have been taken by both Navman users and sourced from professional photo providers, including Lonely Planet . The NavPix Library also enables people to upload non-NavPix images (including other formats such as GIF ) and convert them to NavPix images by using entering either
8927-478: The horizontal, vertical and diagonal axes and moved about in the image. Not all blocks from the original image need to be used in the modified one. The top and left edge of a JPEG image must lie on an 8 × 8 pixel block boundary (or 16 × 16 pixel for larger MCU sizes), but the bottom and right edge need not do so. This limits the possible lossless crop operations, and prevents flips and rotations of an image whose bottom or right edge does not lie on
9040-418: The journal's house style , that all of the referencing and labelling is correct, and that the text is consistent and legible; often this work involves substantive editing and negotiating with the authors. Because the work of academic copy editors can overlap with that of authors' editors , editors employed by journal publishers often refer to themselves as "manuscript editors". During this process, copyright
9153-514: The last two decades has been in the Middle East and Asia with Iran leading with an 11-fold increase followed by the Republic of Korea, Turkey, Cyprus, China, and Oman. In comparison, the only G8 countries in top 20 ranking with fastest performance improvement are, Italy which stands at tenth and Canada at 13th globally. By 2004, it was noted that the output of scientific papers originating from
9266-477: The latitude and longitude they want to associate with the image or by entering the address and using the Library's software to generate the latitude and longitude values based on a Postal code look-up. Unlike some geo-referencing applications, the NavPix Library writes the georeference values to the image itself via the Exif meta data. The photo taking abilities do not help navigation. JPEG This
9379-496: The latter half of the 19th century, and 33% by the first half of the 20th century. The decline in contested claims for priority in research discoveries can be credited to the increasing acceptance of the publication of papers in modern academic journals, with estimates suggesting that around 50 million journal articles have been published since the first appearance of the Philosophical Transactions . The Royal Society
9492-496: The list is U.S. patent 4,698,672 , filed by Compression Labs ' Wen-Hsiung Chen and Daniel J. Klenke in October 1986. The patent describes a DCT-based image compression algorithm, and would later be a cause of controversy in 2002 (see Patent controversy below). However, the JPEG specification did cite two earlier research papers by Wen-Hsiung Chen, published in 1977 and 1984. "JPEG" stands for Joint Photographic Experts Group ,
9605-496: The metadata in an almost-compliant way; the JFIF standard is interpreted somewhat flexibly. Strictly speaking, the JFIF and Exif standards are incompatible, because each specifies that its marker segment (APP0 or APP1, respectively) appear first. In practice, most JPEG files contain a JFIF marker segment that precedes the Exif header. This allows older readers to correctly handle the older format JFIF segment, while newer readers also decode
9718-406: The most widely used image compression standard in the world, and the most widely used digital image format , with several billion JPEG images produced every day as of 2015. The Joint Photographic Experts Group created the standard in 1992. JPEG was largely responsible for the proliferation of digital images and digital photos across the Internet and later social media . JPEG compression
9831-621: The name of the committee that created the JPEG standard and other still picture coding standards. The "Joint" stood for ISO TC97 WG8 and CCITT SGVIII. Founded in 1986, the group developed the JPEG standard during the late 1980s. The group published the JPEG standard in 1992. In 1987, ISO TC 97 became ISO/IEC JTC 1 and, in 1992, CCITT became ITU-T. Currently on the JTC1 side, JPEG is one of two sub-groups of ISO / IEC Joint Technical Committee 1 , Subcommittee 29, Working Group 1 ( ISO/IEC JTC 1/SC 29 /WG 1) – titled as Coding of still pictures . On
9944-489: The number of serials purchased increased an average of only 1.9% per year. Unlike most industries, in academic publishing the two most important inputs are provided "virtually free of charge". These are the articles and the peer review process. Publishers argue that they add value to the publishing process through support to the peer review group, including stipends, as well as through typesetting, printing, and web publishing. Investment analysts, however, have been skeptical of
10057-463: The output bitstream. Nearly all software implementations of JPEG permit user control over the compression ratio (as well as other optional parameters), allowing the user to trade off picture-quality for smaller file size. In embedded applications (such as miniDV, which uses a similar DCT-compression scheme), the parameters are pre-selected and fixed for the application. The compression method is usually lossy , meaning that some original image information
10170-403: The paper version, or even before; sometimes they are also made available to non-subscribers, either immediately (by open access journals ) or after an embargo of anywhere from two to twenty-four months or more, in order to protect against loss of subscriptions. Journals having this delayed availability are sometimes called delayed open access journals . Ellison in 2011 reported that in economics
10283-459: The patent's validity. In light of the reexamination, the accused infringers in four of the five pending lawsuits have filed motions to suspend (stay) their cases until completion of the U.S. Patent and Trademark Office's review of the '341 patent. On April 23, 2008, a judge presiding over the two lawsuits in Chicago, Illinois granted the motions in those cases. On July 22, 2008, the Patent Office issued
10396-578: The patent. Forgent's 2002 announcement created a furor reminiscent of Unisys ' attempts to assert its rights over the GIF image compression standard. The JPEG committee investigated the patent claims in 2002 and were of the opinion that they were invalidated by prior art , a view shared by various experts. Between 2002 and 2004, Forgent was able to obtain about US$ 105 million by licensing their patent to some 30 companies. In April 2004, Forgent sued 31 other companies to enforce further license payments. In July of
10509-570: The prior art, yet it intentionally avoided telling the Patent Office. This makes any appeal to reinstate the patent highly unlikely to succeed. Forgent also possesses a similar patent granted by the European Patent Office in 1994, though it is unclear how enforceable it is. As of October 27, 2006, the U.S. patent's 20-year term appears to have expired, and in November 2006, Forgent agreed to abandon enforcement of patent claims against use of
10622-526: The process of reducing information is called quantization. In simpler terms, quantization is a method for optimally reducing a large number scale (with different occurrences of each number) into a smaller one, and the transform-domain is a convenient representation of the image because the high-frequency coefficients, which contribute less to the overall picture than other coefficients, are characteristically small-values with high compressibility. The quantized coefficients are then sequenced and losslessly packed into
10735-505: The published papers the next year, is smaller although also increasing. Developing countries continue to find ways to improve their share, given research budget constraints and limited resources. There is increasing frustration amongst OA advocates, with what is perceived as resistance to change on the part of many of the established academic publishers. Publishers are often accused of capturing and monetising publicly funded research, using free academic labour for peer review, and then selling
10848-404: The purposes of display on webpages. A JPEG image consists of a sequence of segments , each beginning with a marker , each of which begins with a 0xFF byte, followed by a byte indicating what kind of marker it is. Some markers consist of just those two bytes; others are followed by two bytes (high then low), indicating the length of marker-specific payload data that follows. (The length includes
10961-519: The region's higher education. It has also been argued that good science done by academic institutions who cannot afford to pay for open access might not get published at all, but most open access journals permit the waiver of the fee for financial hardship or authors in underdeveloped countries . In any case, all authors have the option of self-archiving their articles in their institutional repositories or disciplinary repositories in order to make them open access , whether or not they publish them in
11074-501: The resulting publications back to academia at inflated profits. Such frustrations sometimes spill over into hyperbole, of which "publishers add no value" is one of the most common examples. However, scholarly publishing is not a simple process, and publishers do add value to scholarly communication as it is currently designed. Kent Anderson maintains a list of things that journal publishers do which currently contains 102 items and has yet to be formally contested from anyone who challenges
11187-543: The same quality and the edges coincide with block boundaries. The file format known as "JPEG Interchange Format" (JIF) is specified in Annex B of the standard. However, this "pure" file format is rarely used, primarily because of the difficulty of programming encoders and decoders that fully implement all aspects of the standard and because of certain shortcomings of the standard: Several additional standards have evolved to address these issues. The first of these, released in 1992,
11300-704: The same year, a consortium of 21 large computer companies filed a countersuit, with the goal of invalidating the patent. In addition, Microsoft launched a separate lawsuit against Forgent in April 2005. In February 2006, the United States Patent and Trademark Office agreed to re-examine Forgent's JPEG patent at the request of the Public Patent Foundation. On May 26, 2006, the USPTO found the patent invalid based on prior art. The USPTO also found that Forgent knew about
11413-472: The subject. It also gives credit to authors whose work they use and helps avoid plagiarism . The topic of dual publication (also known as self-plagiarism) has been addressed by the Committee on Publication Ethics (COPE), as well as in the research literature itself. Each scholarly journal uses a specific format for citations (also known as references). Among the most common formats used in research papers are
11526-468: The system is essential to quality control in terms of rejecting poor quality work, there have been examples of important results that are turned down by one journal before being taken to others. Rena Steinzor wrote: Perhaps the most widely recognized failing of peer review is its inability to ensure the identification of high-quality work. The list of important scientific papers that were initially rejected by peer-reviewed journals goes back at least as far as
11639-509: The two bytes for the length, but not the two bytes for the marker.) Some markers are followed by entropy-coded data; the length of such a marker does not include the entropy-coded data. Note that consecutive 0xFF bytes are used as fill bytes for padding purposes, although this fill byte padding should only ever take place for markers immediately following entropy-coded scan data (see JPEG specification section B.1.1.2 and E.1.2 for details; specifically "In all cases where markers are appended after
11752-553: The universities and laboratories that employ researchers, endowments set up by discipline or institution, friends of the cause of open access, profits from the sale of add-ons to the basic texts, funds freed up by the demise or cancellation of journals charging traditional subscription or access fees, or even contributions from the researchers themselves". For more recent open public discussion of open access funding models, see Flexible membership funding model for Open Access publishing with no author-facing charges . Prestige journals using
11865-415: The value added by for-profit publishers, as exemplified by a 2005 Deutsche Bank analysis which stated that "we believe the publisher adds relatively little value to the publishing process... We are simply observing that if the process really were as complex, costly and value-added as the publishers protest that it is, 40% margins wouldn't be available." A crisis in academic publishing is "widely perceived";
11978-468: The value of publishers. Many items on the list could be argued to be of value primarily to the publishers themselves, e.g. "Make money and remain a constant in the system of scholarly output". However, others provide direct value to researchers and research in steering the academic literature. This includes arbitrating disputes (e.g. over ethics, authorship), stewarding the scholarly record, copy-editing, proofreading, type-setting, styling of materials, linking
12091-473: The western monopoly of science-publishing, "by August 2021, at least 210,000 new papers on covid-19 had been published, according to a Royal Society study. Of the 720,000-odd authors of these papers, nearly 270,000 were from the US, the UK, Italy or Spain." In the 1960s and 1970s, commercial publishers began to selectively acquire "top-quality" journals that were previously published by nonprofit academic societies. When
12204-541: Was not until the middle of the 20th century that peer review became the standard. The COVID-19 pandemic hijacked the entire world of basic and clinical science, with unprecedented shifts in funding priorities worldwide and a boom in medical publishing, accompanied by an unprecedented increase in the number of publications. Preprints servers become much popular during the pandemic, the Covid situation has an impact also on traditional peer-review . The pandemic has also deepened
12317-462: Was steadfast in its not-yet-popular belief that science could only move forward through a transparent and open exchange of ideas backed by experimental evidence. Early scientific journals embraced several models: some were run by a single individual who exerted editorial control over the contents, often simply publishing extracts from colleagues' letters, while others employed a group decision-making process, more closely aligned to modern peer review. It
12430-499: Was taken. That information is then written into the image's Exif ( Exchangeable image file format ) meta data by the NavPix software . The NavPix, therefore, effectively provides a Georeference of the location where the image was taken, which is not necessarily the same georeference as the object being "NavPix-ed". The NavPix image can then be used to define a destination or point of interest on compatible Navman devices. Furthermore, as
12543-469: Was the JPEG File Interchange Format (or JFIF), followed in recent years by Exchangeable image file format (Exif) and ICC color profiles . Both of these formats use the actual JIF byte layout, consisting of different markers , but in addition, employ one of the JIF standard's extension points, namely the application markers : JFIF uses APP0, while Exif uses APP1. Within these segments of
12656-632: Was unable to replace the original JPEG as the dominant image standard. The original JPEG specification published in 1992 implements processes from various earlier research papers and patents cited by the CCITT (now ITU-T ) and Joint Photographic Experts Group. The JPEG specification cites patents from several companies. The following patents provided the basis for its arithmetic coding algorithm. The JPEG specification also cites three other patents from IBM. Other companies cited as patent holders include AT&T (two patents) and Canon Inc. Absent from
12769-617: Was valid. Global Patent Holdings then filed a number of lawsuits based on claim 17 of its patent. In its first two lawsuits following the reexamination, both filed in Chicago, Illinois, Global Patent Holdings sued the Green Bay Packers , CDW , Motorola , Apple , Orbitz , Officemax , Caterpillar , Kraft and Peapod as defendants. A third lawsuit was filed on December 5, 2007, in South Florida against ADT Security Services , AutoNation , Florida Crystals Corp., HearUSA, MovieTickets.com , Ocwen Financial Corp. and Tire Kingdom , and
