Hi I need your help, can anyone tell me how I could recover the original image from a filtered one knowing the filter impulse response and using the fft2 matlab function. regards Pedro Pedrosa |

Pedro: If , x : original image h : filter's impulse response y: filtered image Then, H = fft2(h); % fourier transform of h Y = fft2(y); % fourier transform of y X = Y./H; % since Y = ( H times X ) x = ifft2(X); % Inverse fourier transform of X Hope this helps, Meenakshi. p3dr0s4 wrote: > Hi > > I need your help, can anyone tell me how I could recover the original > image from a filtered one knowing the filter impulse response and > using the fft2 matlab function. > > regards > > Pedro Pedrosa > > > _____________________________________ > Note: If you do a simple "reply" with your email client, only the > author of this message will receive your answer.
