2-D Image Fourier Transform

This project involves reading in an image (in PGM format) and computing the 2-D FFT of the image.  The intended application is to determine the spatial domain configuration of a wire mesh imprint left on counterfeit money.

The final report project, including software instruction manual can be found here.

Notes/Problems:

When constructing the code for this project, I ran into several pitfalls that I thought I would briefly discuss here to help others avoid making the same mistakes.  Most of these are stupid mistakes that can be avoided by reading documents in detail...but I'm lazy.
