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.

  • If you have to implement it in Python, do you really need an implementation with OpenCV or `scipy` implementation would work too? – Rick M. May 10 '17 at 11:28
  • It doesn't matter how to implement the filtering. Scipy can be a suitable possibility. – A.B. May 11 '17 at 12:04
