| Nosaukums | <p>ISO/IEC 15444-10:2008 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 defined in ISO/IEC 15444-1 and 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 defined in ISO/IEC 15444-1 and ISO/IEC 15444-2. Each encoding or decoding extension is to be used only in combination with particular coding processes and only in accordance with the requirements set forth herein. ISO/IEC 15444-10:2008 also defines extensions to the compressed data format, i.e. interchange format and the abbreviated formats.</p> <p>In particular, for ISO/IEC 15444-2, the following extensions are supported by ISO/IEC 15444-10:2008:</p> <ul> <li>variable DC offset;</li> <li>arbitrary wavelet transform kernels;</li> <li>multi-component transformations;</li> <li>non-linear transformations;</li> <li>region-of-interest.</li> </ul> |
