Abstract
Based on image content, a new watermarking robust algorithm were presented in this paper. A region formed by feature points of the image is used to embed mark. The feature points and region eliminate the effect of geometric distortion, Experiments demonstrate that the technique can well withstand attacks such as rotating, scaling and JPEG lossy compression.
