摘要：
The technique of blind watermarking is one of key technology for copyright protecting. By applying generalized Gaussian distribution to statistically model the Alternating current coefficient of discrete cosine transform, an adaptive blind watermark detection algorithm is presented on the basis of sign detector and linear correlate detector and its probability efficiency is deduced. The experimental results show that the performance of the new detector is better than that of linear correlate detector.
