Class HausdorffDistanceExtractor

Namespace: Emgu.CV.Shape

Assembly: Emgu.CV.dll

A simple Hausdorff distance measure between shapes defined by contours, according to the paper “Comparing Images using the Hausdorff distance.” by D.P. Huttenlocher, G.A. Klanderman, and W.J. Rucklidge. (PAMI 1993).

Constructors

HausdorffDistanceExtractor(DistType, float)

Create Hausdorff distance extractor

public HausdorffDistanceExtractor(DistType distanceFlag = DistType.L2, float rankProp = 0.6)

Parameters

distanceFlag DistType: Rhe norm used to compute the Hausdorff value between two shapes. It can be L1 or L2 norm.
rankProp float: 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.
