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, |

I would like to implement my own log-gabor function in the frequency domain in OpenCV but I have no idea how to do it ... Does one of you have idea ? Or know a tutorial talking about something similar ? Maybe I should you an intermediate library to do this. Thank you ! Bye, |
