约束的最小二乘方图像复原方法的改进

The Improvement of the Image Restoration Method of Restricted Least Square

本文在脉冲响应函数和噪声的第二阶统计未知的条件下，假如预先知道信号的光滑性和支撑区域的信息，用改进的约束最小二乘方方法，复原信号明显地逼近原始信号，并且比一般的最小二乘方方法复原效果更佳。

In the unknown conditions of the pulse response function and the second statistics of noise, if theinformation of the signal smooth and sopport region can be predicted, by the use of the improved restricted leastsquare method, the restored signal approaches obvously the original signal and the restored results are better thanthat obtained by usual least square method.
