信息技术 - Jpeg 2000图像编码系统 - 第1部分:核心编码系统

[中文适用范围]： 本 annex 定义了一个可选文件格式，该格式适用于希望将 JPEG 2000 压缩图像数据打包到其中的应用程序。虽然并非所有应用程序都会使用此格式，但许多应用程序会发现此格式满足其需求。然而，那些实施此文件格式的应用程序应按照本 annex 的描述来实现它。 [外文原描述]： This Recommendation | International Standard 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. This Recommendation | International Standard: ? 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. NOTE ? As this specification was first published as common text only after ISO/IEC JTC1 had approved the first edition in 2000, edition numbers in the ITU and ISO/IEC versions are offset by one. This is the third edition of ITU-T T.800 and the fourth edition of ISO/IEC 15444-1.
