JPEG2000静态数字图像压缩标准下的数字水印分析

摘要

Based on the still image coding standard-JPEG2000, this paper analyzes the parameters that influence the qualities of JPEG2000-compatible images, such as bit rate, tile size, DWT and the process of JPEG2000 compression, and compared them with the ready-made experimental results that are concentrated on JPEG2000 images, the influences of parameters on the watermarking in JPEG2000 domain are presented.%以JPEG2000静态数字图像压缩标准原理为基础,对影响JPEG2000压缩图像的参数如压缩率、tile大小、DWT以及JPEG2000压缩过程进行分析,然后通过对比已有的实验结果,分析了压缩参数对数字水印算法的影响.
