log-gabor frequency filtering with OpenCV

Hi,

I just computed the fft of an image and now I would like to convolute the Fourier transform with a log-gabor frequency filter with different phases, but I have strictly no idea how to do it in OpenCV.

I would like to implement my own log-gabor frequency "kernel" to convolue it with the Fourier transform but I didn't find anything related to it on the internet.

Have you ever done something like that or do you know a tutorial talking about it ? Maybe I have to use an intermediate library to do it ...

Paul,
