DESCRIPTION

ISO/IEC 15444-2:2023

This document 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.

This document:

– 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.
