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.

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...
