摘　　要：通过大量的实验,得出了图像在小波变换域是否失真的判定标准——均方差及其均方差的阈值,进而提出了临界融合的概念,并给出了相应的最大融合算法,该算法使图像的鲁棒性得到很大的提高。实验证明该算法抗图像处理和攻击的能力较强,可应用于数字图像的版权保护和信息隐藏。Through a large number of experiments,the mean square error and its threshold were proposed as the criteria of image distortion in wavelet transform domain.The concept of critical fusion was proposed,and the algorithm for maximum fusion was developed.The algorithm improves image robustness greatly.Experiments prove that the algorithm is capable of resisting image processing and attacks.The algorithm can be used for protecting the copyrights of digital images,and hiding information.
