2d fft image

Hi,

I want to be able to perform a 2D FFT on an image but the only problem the image is coming in line by line. This will require the system to wait for one frame to arrive before performing a 2D FFT. Is there another way of performing a 2D FFT to a real-time image without delaying by a frame?

Hi
If the speed is more important in your design than memory do it:
multiply each row after receive with exp(j2p/NM(nk + ml) and store it in memory. After the end line you can just add properly to form 2D FFT.
I think this method speed up your design.
