CSA Group Information Technology - Digital Compression and Coding of Continuous-Tone Still Images: Extensions (Adopted ISO/IEC 10918-3:1997, first edition, 1997-05-01)

Scope This Recommendation | International Standard is applicable to continuous-tone - grayscale or colour - digital still image data. It is applicable to a wide range of applications which require use of compressed images. This Recommendation | International Standard: defines extensions [including variable quantization, selective refinement, tiling, and a Still Picture Interchange File Format (SPIFF)] to processes for converting source image data to compressed image data defines extensions to processes for converting compresssed image data to reconstructed image data defines coded representations for compressed image data gives guidance and examples on how to implement these extensions in practice describes compliance tests for these extensions.
