Die Annotation des Normtextes ISO/IEC 15444-10-ed.2.0 :

ISO/IEC 15444-10:2011 defines a set of lossless (bit-preserving) and lossy compression methods for coding continuous-tone, bi-level, grey-scale, colour digital volumetric images, or multi-component volumetric images. This set of methods extends the elements in the core coding system described in Rec. ITU-T T.800 | ISO/IEC 15444-1 and Rec. ITU-T T.801 | ISO/IEC 15444-2. Extensions which pertain to encoding and decoding are defined as procedures which may be used in combination with the encoding and decoding processes described in Rec. ITU-T T.800 | ISO/IEC 15444-1 and Rec. ITU-T T.801 | ISO/IEC 15444-2. Each encoding or decoding extension shall be used only in combination with particular coding processes and only in accordance with the requirements set forth herein. ISO/IEC 15444-10:2011 also defines extensions to the compressed data format, i.e. interchange format and the abbreviated formats. In particular, for Rec. ITU-T T.801 | ISO/IEC 15444-2, the following extensions are supported by ISO/IEC 15444-10:2011:

• variable DC offset;
• arbitrary wavelet transform kernels;
• multi-component transformations;
• non-linear transformations;
• region-of-interest.
