Image Restoration Algorithm of Smoothing Constrained Least Square Based on Wavelet Denoising

ZHAO Dong-jie, ZHOU Hui (Brigade 2 of Graduate, Institute of Command & Technology of Equipment, Beijing 101416, China)  
Aiming at the diseased problem of image restoration algorithm of constrained least square with low SNR of degradation image, the image restoration algorithm of smoothing constrained least square based on wavelet denoising was put forward. The steps of the algorithm are as follow: adaptive noise estimation, degradation image wavelet denoising and smoothing constrained least square filter. The step of creating degradation image includes convoluting original image and PSF, joining some additive noise. Experiments prove that the good restoration effect was get using the algorithm, and the SNR of degradation image was decreased obviously.
