Abstract:Generally, feature-based image watermarking uses the local image features present in an image. The invariance of the features is exploited for achieving robustness against attacks, but the leakage of information is often unconsidered. Here an image adaptive watermarking approach is proposed which uses invariant feature regions for enhancing the robustness and security. Feature regions are determined using the scale-adapted auto correlation matrix and the Laplacian-ofGaussian operation. The leakage of the infor… Show more
