Joint Photographic Experts Group

The Joint Photographic Experts Group is the joint committee between Joint Bi-level Image Experts Group.[1][7]

In April 1983, ISO started to work to add photo quality graphics to text terminals. In the mid-1980s, both CCITT (now ITU-T) and ISO had standardization groups for image coding: CCITT Study Group VIII (SG8) – Telematic Services and ISO TC97 SC2 WG8 – Coding of Audio and Picture Information.[8][9] They were historically targeted on image communication. In 1986, it was decided to create the Joint (CCITT/ISO) Photographic Expert Group.[10] The JPEG committee was created in 1986.[11] In 1988, it was decided to create the Joint (CCITT/ISO) Bi-level Image Group (JBIG).[10] The group typically meets three times annually in North America, Asia and Europe. The group often meets jointly with the JBIG committee.[9][12]

Joint Bi-level Image experts Group

The Joint Bi-level Image experts Group (JBIG) is the second sub-group of the same working group (ISO/IEC JTC 1/SC 29/WG 1) as the Joint Photographic Experts Group, which focuses on binary images.[1] They created the JBIG and JBIG2 standard.[7][12]

Standards published and under development

The JPEG (Joint Photographic Experts Group) as a sub-group of ISO/IEC JTC 1/SC 29/WG 1 – Coding of Still Pictures (working as a joint team with ITU-T SG 16) have developed various standards, which have been published by ITU-T and/or ISO/IEC. The standards developed by the JPEG and JBIG sub-groups are referred to as a joint development of ISO/IEC JTC 1/SC 29/WG 1 and ITU-T SG 16. The JPEG standards consist of different Parts. Each part covers a certain aspect of the whole specification. Some of the published JPEG standards were revised by later amendments and/or new editions. Standards developed and under development by JPEG are shown in the table below.
