摘　　要：针对巨型图片恢复处理过程中所面临的运算量庞大的技术瓶颈,从光学图像退化模型出发,发展了一种基于最小二乘方的恢复算法,在算法的实现过程中回避了变换到频域的常规做法,提出了一种新颖的级联模板的运算方法,在一定程度上减小了运算量,降低了复杂度,实验结果表明该方法是有效的。In order to reduce the complexity of calculation while processing large decreased image, an image restoration algorithm based on least square has been developed. When putting it in-to implementation, a new method named ally-template has been proposed, which parrys transform of frequency. Its algorithm architecture is easily implemented. The experimental results demonstrate this approach is effective.
