A Robust Image Watermarking Scheme Based on a Novel HVS Model in Curvelet Domain
Yi Xiao, L.M. Cheng, L. L. Cheng · 2008
In this paper, a robust image watermarking scheme based on curvelet transform is proposed. Considering the frequency and orientational sensitivity of the Human visual System(HVS), we present a HVS model in curvelet domain,which is used to control the embedding strength. The watermark is embedded to the selected coefficients of the curvelet transform, and original image is not required in the extracting process. The experimental results demonstratethat the proposed algorithm can provide excellent robustness against most image processing methods.
