Constructor Detail

opencv_shape.HausdorffDistanceExtractor

public opencv_shape.HausdorffDistanceExtractor(Pointer p)

Pointer cast constructor. Invokes Pointer.Pointer(Pointer).

Method Detail

setDistanceFlag

public void setDistanceFlag(int distanceFlag)

\brief Set the norm used to compute the Hausdorff value between two shapes. It can be L1 or L2 norm.

Parameters:

distanceFlag - Flag indicating which norm is used to compute the Hausdorff distance (NORM_L1, NORM_L2).

getDistanceFlag

public int getDistanceFlag()

setRankProportion

public void setRankProportion(float rankProportion)

\brief This method sets the rank proportion (or fractional value) that establish the Kth ranked value of the partial Hausdorff distance. Experimentally had been shown that 0.6 is a good value to compare shapes.

Parameters:

rankProportion - fractional value (between 0 and 1).

getRankProportion

public float getRankProportion()
