scope:

Tins Recommendation International Standard defines a set of lossless (bit-preserving) and lossy compression methods for coding bi-level, continuous-tone grey-scale. palletized colour, or contmuous-tone colour digital still images.

Tins Recommendation International Standard:

-specifies decoding processes for converting compressed image data to reconstructed image data;

-specifies a codestream syntax containing information for interpreting the compressed image data;

-specifies a file format;

- provides guidance on encoding processes for converting source image data to compressed image data:

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

NOTE - As this specification was first published as common text only after ISO TEC JTC1 had approved the first edition in 2000. edition numbers in the ITU and ISO TEC versions are offset by one. This is the second edition of IITJ-T T.800 and the third edition oflSOIEC 15444-1.
