Abstract: Differing from wavelet transform，Contourlet transform has the ability of image multi-scale and direction decomposition using the anisotropic basis，thus it is better to capture the curve singularity and much more match the HVS properties.A unified robust and perceptual watermarking algorithm is presented with respect to two transform domain.The watermarks are adaptively embedded in each frequency sub-band，with the strength adjusted by the visual saliency of transform coefficients.Some experiments of such algorithm in two multi-resolution decomposition frameworks are given with respect to several common attacks.Experiment results show that the contourlet based algorithm has better safety，robustness and invisible compared with wavelet based algorithm.
