【摘要】 JPEG2000是国际标准化组织(ISO)指定的新一代静止图像压缩标准。它作为JPEG的升级版,向下兼容,具有比JPEG更高的压缩率,同时具有一些新的特征。这里主要介绍了JPEG2000中的核心算法EBCOT(embeddedblockcodingwithoptimizedtruncation)—基于优化截断的嵌入式块编码算法。以此阐述了JPEG2000压缩标准新的特征以及与现有压缩标准相比显示出来的优越性能。更多还原

【Abstract】 JPEG2000 is a new still image compression standard appointed by ISO. As the upgrade of JPEG, the downward compatibility of it has more efficient compression and some new characteristics than that of JPEG. In this paper, we focus on the core algorithm of JPEG2000-EBCOT (embedded block coding with optimized truncation), and describe the new features and the advantages of the JPEG2000 over the previous standard.更多还原
