The normalization for the inverse Fourier transform (ifft2) is got by multiplying by f2=ifft2(F)*sqrt(M*N); f2=real(f2);% chopping small complex values due
The MAtlAB routines for computing the 2-D DFT and the inverse 2-D DFT are the routines fft2 and ifft2. Using the image files hardware.tif shuttle.tif
B = fft2(bluegill). K = fft2(kernel). C = B * K convolved = ifft2(C) deconved = ifft2(C / K) show_image(deconved). What will the resulting image look like?
mMap2=abs(ifft2((Amp2-Amp1).*exp(i*Phase2)));. mMap=mat2gray(mMap1.*mMap2);. Frame1 and Frame2 are consecutive frames. In our experiment the size of.
Case A) FFT2.mex and IFFT2.mex. Mex file in C with CUDA FFT functions. Standard mex script could be used. Overall effort: few hours.
