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 关键词JPEG2000小波变换EBCOT彩色图像编码-Abstract multimedia technology with the increasing use of image compression technology not only requires a high compression performance, but also demand new features to meet some special requirements for this ISO designation of a new generation of still image compression standard JPEG2000 Based on JPEG2000 core of the algorithm in detail EBCOT detailed analysis expounded JPEG2000 compression standard and the new features with the existing compression standard compared to demonstrate the superiority can Keywords JPEG2000 wavelet transform EBCOT Color Image Coding
