2DFFT implementation for image Cross-correlation

Hi there,

For performing stereo image matching by using cross-correlation with 2DFFT on TMS320C6474 platform i required a reference code in C. If someone is there working with it please provide me some reference code for understanding.

I have already performed it in spatial domain now require to experience frequency domain to compare performance. Please help me if you can.

Thanks,
:Rahul

I strongly recommend that you obtain a copy of the book "The Fast Fourier Transform and its Applications" by E. Oran
Brigham:

http://portal.acm.org/citation.cfm?idG314

There is a section on 2-D convolution and correlation using FFT, including a one-page code example.

As you can see from the above page, this book is widely cited. It explains the FFT and ways to use it in practical
and straightforward manner.

Jeff,

Thanks for the book reference.
It is one I did not have.
I just ordered it from Amazon.
