MATLAB Program 5
%fourier transform of 2 diff alphanumeric chars & their correlation by fft2 function
I = imread('apple1.bmp');
d = fft2(BW1.*BW2);
%S = P*BW2;
%Q = fft2(S,3,3);
d = fspecial('gaussian');
figure, freqz2(d,[64 64]), axis([-1 1 -1 1 0 1.3])
First of all both the alphabets are read in I & J . Then fast fourier transform of the individual alphabets and the product of first alphabet & the complex conjugate of second alphabet is performed . Results are shown in fig1, fig2 ,fig3 & fig4 respectively.
