A definition of JPEG 2000
An extension of the current JPEG standard, designed as an ultimate replacement. JPEG 2000 uses a different method of compression than JPEG and has a wider support for different colour spaces, while also offering both lossy and lossless methods of compression (JPEGs are almost always compressed in the lossy format). As of yet it hasn’t been as widely adopted as hoped, although it is used in medical and forensic photography, in addition to certain other imaging industries.
