To the copyright issues of digital image,a novel method of mean quantization digital w atermarking based on lifting w avelet transform is presented. This method combines lifting w avelet transform and mean quantization,it firstly scrambles the w atermarking image through Arnold transform,then it divides the pel matrix of original image into small pieces and takes lifting w avelet transform.After that,it takes mean quantization process on the low frequency coefficient of w avelet to achieve the embedding and...
