Python:
retval=cv.face.BIF_create([, num_bands[, num_rotations]])
Parameters
num_bandsThe number of filter bands (<=8) used for computing BIF.
num_rotationsThe number of image rotations for computing BIF.
Returns
Object for computing BIF.

◆ getNumBands()

virtual int cv::face::BIF::getNumBands ( ) const
pure virtual
Python:
retval=cv.face_BIF.getNumBands()
Returns
