BS ISO/IEC 15444-2:2004 - Page 10

BS 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.

This 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.
