Information technology -- Lossless and near-lossless compression of continuous-tone still images: Extensions

This standard was last reviewed* in 2008.

*ISO standards are reviewed every five years.

Abstract

ISO/IEC 14495-2:2003 defines a set of lossless (bit-preserving) and nearly lossless (where the error for each reconstructed sample is bounded by a predefined value) compression methods for coding continuous-tone (including bi-level), gray-scale, or colour digital still images.

ISO/IEC 14495-2:2003:

  • specifies extensions (including arithmetic coding, extension of near lossless coding, extension of prediction and extension of Golomb coding) to processes for converting source image data to compressed image data;
  • specifies extensions to processes for converting compressed image data to reconstructed image data including an extension for sample tranformation for inverse colour transforms;
  • specifies coded representations for compressed image data;
  • provides guidance on how to implement these processes in practice.
