Hello everyone, I'm in the process of writing a console app, where a user uploads a picture, then clicks a button, and the Fourier transform of the picture displays. I have everything set up except for the FFT algorithm itself. My first question is what value do you get from a pixel to plug into the algorithm? Like in the loop, when i grab my first numerical value from the picture to plug into the algorithm, what is it? Something involving the magnitude of the RGB values? Also, once the FFT has been applied you end up with complex numbers. Is the magnitude used for the new data value? Lastly, once you get your transformed function, how do the values get translated to something that can be redrawn(kind of relates to my first question)?
Thanks in advance for any help.
