Affine Legendre Moment Invariants for Image Watermarking Robust to Geometric Distortions

Geometric distortions are generally simple and effective attacks for many watermarking methods. They can make detection and extraction of the embedded watermark difficult or even impossible by destroying the synchronization between the watermark reader and the embedded watermark. In this paper, we p...
