摘　　要：提出一种基于小波分解的盲图象恢复算法。该算法根据图象小波变换各个子频段所具有的不同频率特性和不同的方向特性,对各子频段分别进行盲图象恢复;各子频段采用不同的正则化算子。实验结果表明该算法的盲图象恢复的性能优于空域算法。A blind image restoration algorithm with smooth constraint based on wa velet decomposition is proposed. According to the different frequency and direct ion property of sub-band, each sub-band degradation image is restored, and the d ifferent smooth factors are used in the different sub-band. The experiment resul ts show that the proposed algorithm is superior to the general spatial domain in the quality of the restored image.
