JPEG2000数字图像压缩标准技术解析
首发时间:2007-11-30
摘要:随着多媒体技术应用的不断增加,图像压缩技术不仅要求具有较高的压缩性能,而且还要求有新的特征来满足一些特殊的要求。为此,国际标准化组织(ISO)指定了新一代静止图像压缩标准:JPEG2000。本文通过对JPEG2000中核心算法(EBCOT)的详细分析,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。

Analysis of JPEG2000 Digital Image Compression Standard
Abstract:With the continuous increase of multimedia applications, image compression technology requires not only high compression performance, but also requires new features to meet some special requirements. To this end, the International Organization for Standardization (ISO) appointed a new generation of still image compression standard:. Based on the detailed analysis of JPEG2000 core algorithm----EBCOT , this paper displayed JPEG2000’s new features and tremendous performance improvements compared with the existing compression standards.
