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.
