ISO/IEC 15444-2:2004 PDF

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.
