Abstract: The robustness of a watermark is determined by the watermark strength. The adjustment of the watermark intensity is made manually now, it is suitable for a few images. In this paper, a method that can automate adjustment of watermark intensity based on the measurement of image texture is proposed, it is suitable for a larger number of images. The results of our experiments show that it is practicable to predict the watermark strength to be applied to an image based on its texture.
