标准摘要
[中文适用范围]: 此建议|国际标准定义了一组无损(位保留)和有损压缩方法,用于编码双层、连续色调灰度、调色板颜色或连续色调彩色数字静态图像。 此建议|国际标准: – 规定将压缩图像数据转换为重建图像数据的解码过程; – 指定包含用于解释压缩图像数据的信息的码流语法; – 指定文件格式; – 提供有关将源图像数据转换为压缩图像数据的编码过程的指导; – 提供有关如何在实践中实施这些流程的指导。 [外文原描述]: ISO/IEC 15444-1:2004 | ITU-T Rec. T.800 defines a set of lossless (bit-preserving) and lossy compression methods for coding bi-level, continuous-tone grey-scale, palletized colour, or continuous-tone colour digital still images. ISO/IEC 15444-1:2004 | ITU-T Rec. T.800 specifies decoding processes for converting compressed image data to reconstructed image data;specifies a codestream syntax containing information for interpreting the compressed image data;specifies a file format;provides guidance on encoding processes for converting source image data to compressed image data;provides guidance on how to implement these processes in practice.
