摘要
研究了几种经典图像复原算法,在已知系统退化模型的情况下,对观测图像分别使用逆滤波、维纳滤波、有约束的最小二乘方滤波算法进行复原,在这几种算法的参数选取上得到了丰富的经验数据,并对实验结果进行了分析总结。
Several classical image restoration algorithms are studied.In the case of knowing the model of the image degradation,the observed images are restored using inverse filtering,Wiener filtering and constrained least squares filtering algorithm.A wealth of empirical data on the parameter selection of the above algorithms is obtained,and the experimental results are analyzed and summarized.
