| 摘 要： | 利用Shannon熵准则选取最优小波包基,分别对原始图像和水印图像进行小波包分解,把水印数据嵌入选定的原始图像小波包基中.实验结果表明,该算法水印信息嵌入量大,不可感知性好,对JPEG压缩有较好的鲁棒性.

| Abstract: | This paper presents a digital watermarking algorithm based on wavelet packet decomposition.This algorithm selects the best basis of the wavelet packet according to Shannon entropy criterion.The host image and the original watermark image are decomposed into two levels wavelet packet.The experimental results show that proposed method is good at invisibility and robust to JPEG image compression. |
