ISO International Standard

This Recommendation | International Standard defines a set of lossless (bit-preserving) and nearly lossless (where the

error for each reconstructed sample is bounded by a pre-defined value) compression methods for coding continuoustone,

gray-scale, or colour digital still images.

This Recommendation | International Standard

? specifies a process for converting source image data to compressed image data;

? specifies processes for converting compressed image data to reconstructed image data;

? specifies coded representations for compressed image data;

? provides guidance on how to implement these processes in practice.
