Abstract
In this paper, we propose a watermarking algorithm for digital image based on DCT and SVD. The algorithm can satisfy the transparence and robustness of the watermarking system very well. The experiment based on this algorithm demonstrates that the watermarking is robust to the common signal processing techniques including JEPG compressing,noise, low pass filter, median filter, contrast enhance.Experimental results show that the new watermarking scheme is more robust than the SVD methods.
