Why fourier transform(dft) is not possible on color images? Why only on gray scale images Fourier transforms is possible?
The Fourier Transform works with the intensity of a signal in time or space and converts to intensities of a signal in frequency. There’s no single number that can represent the intensity of a color without converting to grayscale.
You can split your image into 3 different images, one for each of the Red, Green, and Blue components. Each of those can be processed with a Fourier Transform independently.
