In this paper, a digital image watermarking scheme based on singular value decomposition (SVD) and principal component analysis (PCA) is proposed. Firstly, the reconstruction image of initial image is obtained by use of PCA. Secondly, the reconstruction image is divided into blocks according to the size of the watermark and each block is transformed by using SVD. Then, the watermark is embedded into the corresponding blocks of the reconstruction image. Experimental results show the robustness of the proposed scheme to a variety of general image processing , especially to cropping and JPEG compression.
