Method Detail

create

@opencv_core.Ptr
public static AffineFeature create(@opencv_core.Ptr
                                                     Feature2D backend,
                                                     int maxTilt,
                                                     int minTilt,
                                                     float tiltStep,
                                                     float rotateStepBase)

Parameters:

backend - The detector/extractor you want to use as backend.

maxTilt - The highest power index of tilt factor. 5 is used in the paper as tilt sampling range n.

minTilt - The lowest power index of tilt factor. 0 is used in the paper.

tiltStep - Tilt sampling step \delta_t in Algorithm 1 in the paper.

rotateStepBase - Rotation sampling step factor b in Algorithm 1 in the paper.
