Abstract

Watermarking resisting to geometric distortion is a very difficult and challenging subject. In this paper, to solve this problem, two method are proposed one method, which estimates rotation and scaling based on template embedding, has low computing complexity for template matching, one method which estimates translation based on invariant centriod has solve the translation synchronization of the original watermarking images and test images. Experiments demonstrate that the scheme is can efficiently correct geometric distortions of high intensity.
