标准摘要
[中文适用范围]： 本文件定义了一组图像压缩方法，适用于单色、连续色调灰度、连续色调颜色或多通道数字样本的编码。本文件：——指定了解码过程，用于将压缩的图像数据转换为重建的图像数据；——规定了包含解释压缩图像数据信息的码流语法；——提供了关于如何将原始图像数据转换为压缩图像数据的指导过程。 [外文原描述]： This document defines a set of compression methods for coding one or more images of bi-level, continuous-tone greyscale, or continuous-tone colour, or multichannel digital samples. This document: — specifies decoding processes for converting compressed image data to reconstructed image data; — specifies a codestream syntax containing information for interpreting the compressed image data; — provides guidance on encoding processes for converting source image data to compressed image data.
