摘要：This paper proposes a color image watermarking algorithm which combines Tucker decomposition and HOSVD decomposition. The DC component, which comes from DCT transform, is constructed 3-level tensor. A core tensor is got from Tucker decomposition. The singular values are obtained from HOSVD decomposition and the singular values are modified to hide the watermark information. The conventional image processing (noise, filtering, zoom) and shear attacks experimental results show that the color image watermarking algorithm has better robustness and invisibility, compared with the conventional color image watermarking algorithm and the existing high-dimensional data decomposition algorithm. ? 2013 by Binary Information Press.
