Overview of JPEG-LS

JPEG-LS was defined to address the need for effective lossless and near-lossless compression of continuous-tone still images. This standard can be broken into two parts: ISO/IEC 14495-1:1999 | ITU-T Rec. T.87 (1998), defining the core technology and ISO/IEC 14495-2:2003 | ITU-T Rec. T.870 (03/2002), containing the extensions. JPEG-LS is especially suited for low-complexity hardware implementations of very moderate complexity, while at the same time providing state-of-the-art lossless compression performance.
