title(\'disk\')

G3=imnoise(disk,\'gaussian\',0,0.001);

LR2=deconvlucy(G3,H1,10)
subplot(3,4,11);

title(\'disk+noise复原\');

H2=fspecial(\'unsharp\'); %钝化模糊的偏移矩阵
unsharp=imfilter(I,H2); %卷积
subplot(344);
imshow(unsharp);
title(\'unsharp\')

G4=imnoise(unsharp,\'gaussian\',0,0.005);

LR3=deconvlucy(G4,H2,5)

imshow(LR3);
title(\'unsharp+noise复原\');

　　

 

感觉只是对光学聚焦模糊有比较好的效果吧。。
