Abstract
For improving the visibility and resistance of offensive attack, submitting a new digital watermarking algorithm based on Contourlet and SVD. Using traits of the Contourlet: change-multi-directions and anisotropy, use the Contourlet change to the image, singular value of low frequency component is decomposed, and then embed the watermark image into the singular decomposition matrix, make the watermark image has more visibility, and resistance to the attack of offensive.
