matlab实现维纳滤波逆滤波

function [target] = blurring(raw) [h,w] = size(raw); [Y,X] = meshgrid(1:w,1:h); a = (im2double(raw)).*(-1).^(X+Y); b = fft2(a); %imshow(log(1+abs(b)),[]); [U,V] = meshgrid(-344:1:343,-344:1:343); H = (1./(0.1*pi*(U+V+0.1)).*sin(0.1*pi*(U+V+0.1))).*exp(-i*0.1*pi*(U+V+0.1)); % imshow(log(1+abs(H)),[]); c = H.*b; % imshow(log(1+abs(c)),[]); d = real(ifft2(c)); e = d.*(-1).^(X+Y); target = e;
