how to find the Fourier transform of the color image? & how to extract feature of color image by using fractional Fourier transform?

David Young 2011-8-30

Use fft2 on each of the colour planes in turn, for example

Ft_image(:,:,1) = fft2(Image(:,:,1));
Ft_image(:,:,2) = fft2(Image(:,:,2));
Ft_image(:,:,3) = fft2(Image(:,:,3));

(assuming that you don't want the Fourier transform in colour space - I don't think that would make sense).

I don't know about the fractional Fourier transform.

that's right but i wanted to know how to find the fractional Fourier transform of color image
