摘要
近年来,随着多种图像数字水印算法的提出,有必要建立一系列评估算法性能的标准。文章提出了检验图像水印算法稳健性和透明度的建议标准,包括测试对象、评估标准及一系列攻击方法,并给出了空域法和基于小波法下的图像水印质量的评估结果。
In the last few years,digital watermarks have been proposed as a solution for solving the illegal copying and proof of ownership problem in the context of multimedia objects.But it is still difficult to have a rough standard of their performances and hence to compare them.So we propose a benchmark to compare image watermarking on a fair basis.
