scikit-image fft

Hi all, Discovered sci-image recently, and I like it so far. Right now I am basically trying to do an fft, filter out certain frequencies, and then back transform it to an image. My first thought was to use fft, but I can't find an fft function in the docs. I see that numpy has an fft function, but running that on a sci-kit image gives unpleasant errors. Is there perhaps a better method for this than fft? Any suggestions? chris
