用deconvwnr作图像恢复问题请教
用deconvwnr作图像恢复已知高斯，出现如下问题：做图像恢复，已知图像已经用gaussian low pass filter 处理了，size256, sigama 40，并且Thefilter was re-scaled such that its maximum value was equal to1，现在想deblur，编了个小程序，但恢复的效果很差。。。不知道为什么？

源程序：
A=imread(inputfile);
PSF = fspecial('Gaussian', ,40);
%PSF=PSF/(max(max(PSF)));
wnr1 = deconvwnr(A,PSF);
figure;
subplot(1,2,1);imshow(A);
subplot(1,2,2);imshow(wnr1,[]);
