A new RST-invariant watermarking scheme based on texture features

Abstract

Robustness and imperceptibility are two fundamental criteria for digital watermarking algorithm. In this paper, we present a new RST-invariant (rotation, scaling, and translation) digital image watermarking scheme to embed and detect watermark in DFT domain, which is based on image texture features and the corresponding wedge curves. Experimental evaluations have demonstrated that the proposed scheme performs imperceptibility watermarking of images and the embedded watermark is good resilient to various common geometric attacks.
