嵌入水印系数的选取对PSNR的影响

The Discussion of PSNR When Choicing the Different Methods of Embedding Coefficient

通过讨论几种不同的小波分块中系数选取的方法,给出一种相对较优的顺序系数选取策略。实验证明,使用该算法嵌入水印具有良好的鲁棒性和不可见性。

In the paper, we discuss the different methods of embedding coefficient and propose a optimum style of choosing coefficient. The experiments proved that the algorithm presented in paper have strong robustness and good invisibility.
