fft - how to find the peak(r,theta) from DFT spectrum in matlab? - suppose have matrix m apply dft on , shift centre img_fft = fft2(double(m)); img_spec = abs(img_fft); img_shift = fftshift(img_spec); then according question, how find peak of spectrum ,i.e. (u,v) of peak? lot! use find determine in image maximum value occurs. however, question says ignore dc value, largest component in spectrum far. such, should find maximum value, should dc value currently, , set nan . 1 time this, next maximum value you're searching reply question. as such, first: idx = find(img_shift == max(img_shift(:))); img_shift(idx) = nan; if set maximum value here nan , next time phone call find , disregard location , skip location when searching maximum value. now, phone call find again: [u,v] = find(img_shift == max(img_shift(:))); here, u horizontal location of image while v vertical position. should homecoming maximum peak not dc value. however, isn...
