JPEG 2000 (JP2) is an image compression standard and coding system. It was developed from 1997 to 2000 by a Joint Photographic Experts Group committee chaired by Touradj Ebrahimi (later the JPEG president), [1] with the intention of superseding their original JPEG standard (created in 1992), which is based on a discrete cosine transform (DCT), with a newly designed, wavelet-based method.
JPEG 2000's lossless mode runs more slowly and has often worse compression ratios than JPEG LS on artificial and compound images [12] [13] but fares better than the UBC implementation of JPEG LS on digital camera pictures. [14] JPEG 2000 is also scalable, progressive, and more widely implemented. [citation needed]
Continuously varied JPEG compression (between Q=100 and Q=1) for an abdominal CT scan. JPEG (/ ˈ dʒ eɪ p ɛ ɡ / JAY-peg, short for Joint Photographic Experts Group and sometimes retroactively referred to as JPEG 1) [2] [3] is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography.
Image compression is a type of data compression applied to digital images, to reduce their cost for storage or transmission. Algorithms may take advantage of visual perception and the statistical properties of image data to provide superior results compared with generic data compression methods which are used for other digital data.

CCSDS 122.0 is a CCSDS lossless to lossy image compression standard originally released in November 2005. The encoder consists of two parts—a discrete wavelet transform transform coder followed by a bitplane encoder on the similar lines as Embedded Zerotree Wavelet by Shapiro.
