converting image to frequency domai using FFt - subh...@yahoo.com - Aug 15 6:32:00 2005



hi
Iam doing a project in image processing where i have to convert an image innto freuency domain.The problem is that all the fft programs take complex as input.Can some one tell me how to convert an image into complex format.
Thanks

Sam

There some fft implementations which do the processing on real valued signals .... but if you do want to work with complex signals then try using the Hilbert transform.....
