摘要: Many digital watermarks now available for images are sensitive to geometric distortions, which particularly prevent blind detection of a public watermark. In this paper, watermarking algorithm based on singular value decomposition (SVD) is proposed, robust common distortions. The watermark embedded into image's values. By the algebraic properties SVD, it proved rigorously that values watermarked image invariant when goes through distortions transpose, mirror reflection, rotation, scale, and translation. Experimental results show performs well in robustness. can be detected reliably, following these usual signal processing, or JPEG compression.
