ISO/IEC 15444-2:2004 defines a set of lossless (bit-preserving) and lossy compression methods for coding continuous-tone, bi-level, grey-scale, colour digital still images, or multi-component images.
ISO/IEC 15444-2:2004:
specifies extended decoding processes for converting compressed image data to reconstructed image data;specifies an extended codestream syntax containing information for interpreting the compressed image data;specifies an extended file format;specifies a container to store image metadata;defines a standard set of image metadata;provides guidance on extended encoding processes for converting source image data to compressed image data;provides guidance on how to implement these processes in practice.
