Abstract: In this paper, a novel copyright protection method that combines the Singular Value Decomposition (SVD) and the Dual Tree Complex Wavelet Transform (DT-CWT) is presented. After applying the 2-level DT-CWT to the original image, we apply the SVD to each high-pass subband obtained. The singular values in each subband are then modified by the singular values of the DT-CWT- transformed watermark. Experimental results demonstrate that the proposed scheme can effectively resist several common attacks.
