摘要：Image Watermarking has become an important technique nowadays for the copyright protection. In this paper, a new wavelet-based watermarking scheme is proposed. The experimental results show the efficiency of the watermarking scheme, which emphasize a good combination between Gaussian noise and Daubechies wavelet. The PSNR (Peak signal to noise ratio) index is used to perform the evaluation of watermarking between host and watermarked images. For a set of ten sequential images a significant increase in the PSNR value is observed when the images contain a higher gray pixels area.
