Abstract

One of the methods for detecting watermarks after geometrical distortions is correcting distorted watermarked image before detecting. In this paper, a definition of weight Hausdorff distance is defined. It is applied to evaluation the similarity between original and geometric distorted watermarking image. A fast divide and conquer strategy in six dimension is used to search the transformation parameters. The geometric distortion is corrected by the parameters. As a result, a distorted watermarking image could be corrected based on image feature.
