How do I clean up an imagine after doing a 2d FFT?

[Orynn]

I'm loading images of 512x512, and running an FFT first by rows, then by columns. Unfortunatley, due to needing to square both the real and imaginary, and adding them, my values result in being very high. I cannot get a proper image of the transformation. I've tried taking the square root twice on each operation, and while I am getting color values on my graph, the transform is no longer useful, as everything has been blurred together. Any thoughts? Thanks.

Hi Orynn

Are you using the FFT functionality of Measurement Studio? Or are you writing your own FFT function? Also, if you have a small piece of example code that you can post, we can take a look at it and see what might be going on.

Thanks for the offer, but i found after much confusion how to get an accurate set of data.
