信息技术.JPEG2000图像编码系统.第1部分:核心编码系统

[中文适用范围]： 本附录定义了一个可选文件格式，供应用程序选择使用以包装JPEG 2000压缩图像数据。尽管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符合其需求。然而，实施此文件格式的应用程序应按照本附件的描述进行实施。 [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.
