| Abstract: | In this paper, an adaptive watermarking scheme based on the general Gauss distribution model of wavelet coefficients is proposed. With the estimate of the shape parameter of subset of wavelet eoefficients, a locally optumum detection is used. It is adaptive detection to the images and the subset of the coefficients. It is shown with experiments that the new blind watermarking scheme both has the good transparency and robustness. |
