The Exif and JFIF standards define the commonly used file formats for interchange of JPEG-compressed images. The JPEG standard specifies the codec, which defines how an image is compressed into a stream of bytes and decompressed back into an image, but not the file format used to contain that stream. The original JPEG group was organized in 1986, issuing the first JPEG standard in 1992, which was approved in September 1992 as ITU-T Recommendation T.81 and in 1994 as ISO/ IEC 10918-1. On the ITU-T side ITU-T SG16 is the respective body. 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.
In 1987 ISO TC 97 became ISO/IEC JTC1 and in 1992 CCITT became ITU-T. The "Joint" stood for ISO TC97 WG8 and CCITT SGVIII. The name "JPEG" stands for Joint Photographic Experts Group, the name of the committee that created the JPEG standard and also other still picture coding standards. It supports a maximum image size of 65535Ã-65535. The MIME media type for JPEG is image/jpeg (defined in RFC 1341), except in Internet Explorer, which provides a MIME type of image/pjpeg when uploading JPEG images. The term "JPEG" is an acronym for the Joint Photographic Experts Group, which created the standard. These format variations are often not distinguished, and are simply called JPEG. JPEG/ Exif is the most common image format used by digital cameras and other photographic image capture devices along with JPEG/JFIF, it is the most common format for storing and transmitting photographic images on the World Wide Web. JPEG compression is used in a number of image file formats. JPEG typically achieves 10:1 compression with little perceptible loss in image quality. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. In computing, JPEG ( pron.: / ˈ dÊ’ eɪ p É› É¡ / JAY-peg) is a commonly used method of lossy compression for digital photography (image). On Saturday they held a candle-lit vigil in central Madrid to keep up the momentum.Continuously varied JPEG compression (between Q=100 and Q=0) for an abdominal CT scan. The protests of Spain’s youth-led indignado movement have sparked similar movements across Europe. And it is the young that appear to be taking the brunt of the downturn – nearly half of them are unemployed.
Thousands of supporters gathered for a final rally on Friday night but the jobless rate, the country’s huge debts and increasing borrowing costs have all taken their toll. Rubalcaba has all but admitted that the election is lost. He has promised to get Spain’s economy working again and reduce unemployment which stands at around 5 million – twice as high as the rest of the EU. If the polls are anything to go by then Rajoy will win and end eight years of socialist rule. It has been a campaign led by economic issues and the people have to decide which of the two candidates can best restore Spain’s fortunes in the face of the growing euro zone crisis -the socialist candidate Alfredo Perez Rubalcaba, or the conservative Popular Party leader Mariano Rajoy.
Schools have been turned into polling stations and the ballot papers and boxes have been delivered ready for up to 36 million voters make their choice. Final preparations are in place for Spain’s general election.
