Abstract: The computation of the channel capacity of digital watermarking is very difficult. By statistical prior model of image wavelet coefficient and iteration methods of channel capacity in the information theory, this paper derives a kind of computation of multiply watermarking channel capacity in the wavelet domain .

Key words: Digital Watermarking, Channel Capacity, Information Theory

摘要: 数字水印信道容量的计算是一个十分困难的课题。本文通过建立小波域图像的统计先验模型和应用信息论中信道容量的递代计算方法,给出了一类小波域图像乘性水印信道容量的数值计算方法和实验结果。
