Abstract

In this paper, a novel watermarking scheme is proposed by embedding a gray-scale watermark into gray-scale images. The proposed scheme is a Hybrid watermarking algorithm based on singular value decomposition (SVD) and Steerable Pyramid (SP) wavelet transform. The robustness of the proposed method is evaluated by executing various image processing attacks. Peak signal to noise ratio (PSNR) is used to examine the image quality before and after the embedding process. Experimental results show that the proposed watermarking scheme is robust against various attacks.
