A watermarking algorithm based on the SVD and Hadamard transform

Digital watermarking is deemed as a novel technique for copyright of digital products and has aroused extensive interest in recent years. Based on the properties of the Hadamard transform and the singular value decomposition (SVD), this paper proposes a novel watermarking algorithm, the experimental results showing that the watermarking algorithm has good transparency and robustness, especially against the geometrical operations and JPEG lossy compression.
