Abstract

This paper present a method based on gradient texture watermark. This method uses the feature that the image gradient map reflects the change of image texture very well to estimate the image texture complexity and power with the average power of gradient map and variance and to embed the robust watermark in good texture complexity. Experiment shows that the algorithm resist the normal video watermark attack, and has good invisibility.
