Gabor kernel not normalized - feature or bug?
The Gabor kernel created by the new getGaborKernel() does not normalize its coefficients to 1. Their sum is usually extremely low (from 0.3f to 10e-10), and some of the values I think are denormals.
Is it the expected behaviour of Gabor filters? Given the fact that they are usually applied on images, and the result is expected to fit into the uchar datatype, I wonder whether this is a bug...
I think you have a bug. My Gabor kernel seems normalizes and its values are of (-1, 1), none seems too big nor too small.
