Gabor kernel parameters in OpenCV

I must use Gabor filter in my application, but I have no clue about this OpenCV methods parameters values. I want to encoding an iris. Start of Gabor filter and get features (I want to do this for 12 sets of Gabor parameters values). Then I want to count a Hamming dystans and do authentication.

If someone could write here params ranges, or way how to calculate it in function:

Imgproc.getGaborKernel(new Size(kSize[j], kSize[j]), sigma, theta, lambda, gamma); I'll be very grateful. Of course I have tried to assign it myself, but without success.

Example file:
