Combining SVD-DCT Image Watermarking Scheme Based on Perona-Malik Diffusion
In this paper, we propose an efficient image watermarking scheme based on combining Singular Value Decomposition (SVD) and Discrete Cosine Transform (DCT) transforms. The main idea consists of exploiting results obtained by the well-known Perona-Malik diffusion applied in image de-noising in waterma...
