标准摘要
[中文适用范围]: ITU-T 建议书。 T.809 | ISO/IEC 15444-10 是 ISO/IEC 15444 的工作项细分,提供 ITU-T Rec. 的扩展。 T.800 | ISO/IEC 15444-1 和 ITU-T 建议书。 T.801 | ISO/IEC 15444-2 用于逻辑立方体数据集。 特别是,它尊重 ITU-T Rec. 的所有现有功能和语法。 T.800 | ISO/IEC 15444-1 和 ITU-T Rec. 的部分现有功能T.801 | ISO/IEC 15444-2 适用于多组件图像,同时为其中一些功能提供替代方案和扩展。 在这些约束内,它为三维数据集提供了各向同性规范;即,该项目在所有三个维度上提供相同的处理能力,即使 ITU-T Rec. T.800 | ISO/IEC 15444-1 和 ITU-T 建议书。 T.801 | ISO/IEC 15444-2 码流语法区分两个空间轴和交叉分量轴。 本建议书当前使用的上下文模型 |国际标准如 ITU-T Rec. 所示。 T.800 | ISO/IEC 15444-1 和 ITU-T 建议书。 T.801 | ISO/IEC 15444-2。 将通过修正案引入改进的上下文模型。 [外文原描述]: 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. In particular, for ISO/IEC 15444-2, the following extensions are supported by ISO/IEC 15444-10:2008: variable DC offset; arbitrary wavelet transform kernels; multi-component transformations; non-linear transformations; region-of-interest.
