ISO/IEC 15444-10:20 08定义了一组用于编码连续色调、双层、灰度、彩色数字体积图像或多分量体积图像的无损(比特保留)和有损压缩方法。这组方法扩展了ISO/IEC 15444-1和ISO/IEC 15444-2中定义的核心编码系统中的元素。与编码和解码有关的扩展被定义为可以与ISO/IEC 15444-1和ISO/IEC 15444-2中定义的编码和解码过程结合使用的过程。每个编码或解码扩展仅与特定编码过程结合使用，并且仅根据本文阐述的要求使用。ISO/IEC 15444-10:20 08还定义了压缩数据格式的扩展，即交换格式和缩写格式。特别是，对于ISO/IEC 15444-2，ISO/IEC 15444-10:20 08支持以下扩展:可变DC偏移；任意小波变换核；多组分变换；非线性变换；感兴趣区域。

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.
