摘　　要：论述了图像质量的客观和主观评价方法。针对贺兰山岩画文物数字图像的保护和安全问题,开展了图像数字水印及图像攻击后质量评价方法的研究,采用峰值信噪比评测了各水印算法。实验结果表明,DWT算法具有较强的健壮性。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.

关 键 词：质量评价 均方误差 峰值信噪比
