Summary

This Recommendation | International Standard 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 Recommendation | International Standard:

–           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.
