%X Many digital watermarks now available for images are sensitive to signal processing and geometric distortions,this paper proposed a robust digital image watermarking algorithm.After decomposing the whole image with 3 level of discrete wavelet transform,then applyed the singular value decomposition(SVD) to the low frequency domain,and embedded the singular values of the watermark image that was decomposed with SVD after chaotic scrambling by modifying the singular values,and embedded the watermark data to th...
