JPEG (Joint Photographic Experts Group)

This was (and is) a group of experts nominated by national standards bodies and major companies to work to produce standards for continuous tone image coding. The 'joint' refers to its status as a committee working on both ISO and ITU-T standards. The 'official' title of the committee is ISO/IEC JTC1 SC29 Working Group 1, and is responsible for both JPEG and JBIG standards. The best known standard from JPEG is ITU-T T.81, which is the first of a multi-part set of standards for still image compression. A basic version of the many features of this standard, in association with a file format placed into the public domain by C-Cube Microsystems (JFIF), is what most people think of as JPEG.
