信息技术.JPEG 2000图像编码系统:三维数据的扩展名

[中文适用范围]： 此推荐|国际标准是 ISO/IEC 15444 的一个工作项目细分，它提供了 Rec 的扩展。 ITU-T T.800 | ISO/IEC 15444-1 和 Rec. ITU-T T.801 | ISO/IEC 15444-2 适用于逻辑立方数据集。特别是，它尊重 Rec 的所有现有功能和语法。 ITU-T T.800 | ISO/IEC 15444-1 和 Rec 的部分现有功能。 ITU-T T.801 | ISO/IEC 15444-2 用于多组件图像，同时为其中一些功能提供替代和扩展。 [外文原描述]： 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.
