Syntax

public class HausdorffSimilarityMeasure : ISimilarityMeasure

Remarks

The measure is normalized to lie in the range [0, 1]. Higher measures indicate a great degree of similarity.

The measure is computed by computing the Hausdorff distance between the input geometries, and then normalizing this by dividing it by the diagonal distance across the envelope of the combined geometries.
