摘要：
Zerotree of wavelet based digital watermarking techniques are considered to be an efficient blind watermarking method, but the difficult of it is the determining of the threshold in watermarking process. A new method based on the types of the image block is presented to solve this problem. Experiment results show the superior performance in both qualities of the watermarked image and robustness of the embedded watermark signal against attacking.
