The Hausdorff Distance is a mathematical construct to measure the "closeness" of two sets of points that are subsets of a metric space.

Such a measure may be used to assign a scalar score to the similarity between two trajectories, data clouds or any sets of points.

This function will return the Hausdorff Distance between two sets of points.

バージョン 公開済み リリース ノート
1.6.0.0

An option for data visualization is now included.
1.4.0.0

Based on user comments, the algorithm for large data sets was updated for performance.
1.3.0.0

The code now automatically switches to a secondary algorithm when there is insufficient memory to compute and store a matrix containing distances between all constituent points. It also allows the user to manually choose the desired algorithm.
1.2.0.0

Generalizes the code to allow N-dimensional point sets. This update is inspired by file 27905, which has a good implementation of HD beyond 2-D sets of points.
1.1.0.0

Edits Added the matrix of distances as an output option. Fixed a bug that would cause an error if one of the sets was a single point. Removed excess calls to "size" and "length". - May 2010
