In order to solve the problem aliasing of Contourlet transform, an Image Fusion Watermarking Algorithm based on NSCT and constrained NMF is proposed in this paper. Firstly, the image is decomposed into several layers. Secondly, the Two-dimension matrix is obtained by low frequency coefficients and watermarking signal. Finally, the watermarking is embedding by constrained NMF. The blind detection is used, and the algorithm can achieve a good imperceptibility. Experimental results show that the algorithm has good robustness against attacks of common image processing.
