Scope:

ISO/IEC 15444-2:2004 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.

ISO/IEC 15444-2:2004:

  • 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.

Project need:

To review the standard for its 5-year review period
