Is anyone aware of a library for phase unwrapping interferogram images using the FFT method and minimum spanning tree approach? If so where. This can be either commercial or freely available under any license.

Ghiglia and Pritt's "Two-Dimensional Phase Unwrapping: Theory, Algorithms, and Software" comes with C source code in the text. I believe you can also download their code via FTP.

See

http://www.amazon.com/Two-Dimensional-Phase-Unwrapping-Algorithms-Software/dp/0471249351/ref=sr_1_1?ie=UTF8&s=books&qid=1268764344&sr=8-1

Their FFT Method 1 can be coded in Matlab from their pseudo-code in less than 50 lines if you want to do it yourself.
