| Abstract: | In this paper, the author discusses the objective standard and the subjective standard of image quality measure.To protect the copyright and securities of Mount Helan rock painting,this paper focuses on the digital watermark technology and the quality measure of attacked image.The author embeds the watermark information into the relic images and test the watermark algorithms by PSNR.The result of experiment indicates that the algorithm of watermark based on DWT is robustness. |
