WebDec 2, 2024 · % Multiply it by the filter. fftOrig and h have DC position at center of image. c1 = fftOrig .* h; % There are some nan's which mess up the inverse transform. Set nan's to zero. rc = real (c1); ic = imag (c1); rc (isnan (rc)) = 0; ic (isnan (ic)) = 0; c1 = rc + 1i * ic; subplot (2, 3, 4); imshow (abs (log (c1)+1), []); Websuch as Weiner filter, Inverse filter, and Constrained Least square filter. Lucy-Richardson algorithm is a Non-linear type of restoration method [7]. 4.1 Direct Inverse Filtering The blurring function of the corrupted image is known or can be developed then it has been proved as quickest and easiest way to restore the distorted image.

But G (u, v) is given by G (u, v) = F (u, v) + N (u, v) Hence
