I have to process a numpy frame using the Homomorphic filtering to obtain the image for FisherFaces, improving the recognition. I need the equivalent Homomorphic filtering in Python language. I've tried to search some functions in OpenCV (v2.4) without finding the solution.
I have also seen this (and many other links): Homomorphic filtering in Cplusplus language. But it hasn't solved my problem.
I hope you'll can help me. Thank you a lot.
