In this paper, a technical description of Part 1 of the JPEG 2000 standard is provided, and the rationale behind the selected technologies is explained. Parts 2вЂ“6 define extensions to both the compression technology and the file format and are currently in various stages of development. From archiving data to CD-ROMs, and from coding theory to image analysis, many facets of computing make use of data compression in one form or another. Officially, JPEG corresponds to the ISO/IEC international standard 10928-1, digital compression and coding of continuous-tone (multilevel) still images. This effort has been known as JPEG, the Joint Photographic Experts Group. JPEGs proposed standard aims to be generic, to support a wide variety of applications for continuous-tone images.

Part 1, in the same vein as the JPEG baseline system, is aimed at minimal complexity and maximal interchange and was issued as an International Standard at the end of 2000. together to establish an international standard for the compression of grayscale and colour still images. A joint ISO/CCITT committee known as JPEG (Joint Photographic Experts Group) has been working to establish the first international compression standard for continuous-tone still images, both grayscale and color. This initiative, which was named JPEG 2000, has resulted in a comprehensive standard (ISO 15444в€ЈITU-T Recommendation T.800) that is being issued in six parts. In 1996, the JPEG committee began to investigate possibilities for a new still image compression standard to serve current and future applications.
