Description / Abstract:
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 compressed
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.
