opencv - How to set Gabor filter parameters to extract wrinkle features -

-

i trying implement wrinkle feature extraction method using gabor filters in opencv c++ outlined in study:

choi, sung eun, et al. "age estimation using hierarchical classifier based on global , local facial features." pattern recognition 44.6 (2011): 1262-1281.

the filters have input patches of skin face image, , need extract thick , fine wrinkles. don't know parameters use wrinkles since examples on internet deal edges formed objects. after getting output image of convolution, need find mean , variance of magnitude response.

it great if found study on forming gabor kernels wrinkles, sample code, or neat way figure out best parameters.
