Abstract:This paper proposes an improving method for the pixelwise based image watermarking by using image averaging technique and prediction of tuned watermarked pixels. To reduce the error in the original pixel prediction process caused by the high different values of neighbor pixels in the watermarked image, the technique of image averaging is applied to host image in the embedding process, and the watermarked image in the extraction process. Furthermore, a tuning technique is implemented to reduce the prediction er… Show more
