matlab6.5图形图像处理源程序.很多的。很好用的。很有帮助的。

I = checkerboard(8);
PSF = fspecial('gaussian',7,10);
%点扩散函数
V = .0001;
BlurredNoisy = imnoise(imfilter(I,PSF),'gaussian',0,V);
%加性噪声
WT = zeros(size(I));
WT(5:end-4,5:end-4) = 1;
J1 = deconvlucy(BlurredNoisy,PSF);
J2 = deconvlucy(BlurredNoisy,PSF,20,sqrt(V));
J3 = deconvlucy(BlurredNoisy,PSF,20,sqrt(V),[],WT);
subplot(221);imshow(BlurredNoisy);
title('A = Blurred and Noisy');
subplot(222);imshow(J1);
title('deconvlucy(A,PSF)');
subplot(223);imshow(J2);
title('deconvlucy(A,PSF,NI,DP)');
subplot(224);imshow(J3);
title('deconvlucy(A,PSF,NI,DP,[],WT)');
