标准摘要
[中文适用范围]: 本建议书 | 国际标准定义了一套无损(比特保留)和有损压缩方法,用于对连续色调、双级、灰度、彩色数字静态图像或多分量图像进行编码。本建议书 | 国际标准: – 规定了将压缩图像数据转换为重构图像数据的扩展解码过程; – 规定了包含用于解释压缩图像数据的信息的扩展码流语法; – 规定了扩展文件格式; – 规定了用于存储图像元数据的容器; – 定义一组标准的图像元数据; – 为将源图像数据转换为压缩图像数据的扩展编码过程提供指导; – 为如何在实践中实施这些过程提供指导。 [外文原描述]: This document defines a set of lossless (bit-preserving) and lossy compression methods for coding continuous-tone, bi-level, grey-scale, colour digital still images, or multi-component images. This document: – specifies extended decoding processes for converting compressed image data to reconstructed image data; – specifies an extended codestream syntax containing information for interpreting the compressed image data; – specifies an extended file format; – specifies a container to store image metadata; – defines a standard set of image metadata; – provides guidance on extended encoding processes for converting source image data to compressed image data; – provides guidance on how to implement these processes in practice.
