rgrl_matcher_k_nearest_boundary Class Reference

#include <rgrl_matcher_k_nearest_boundary.h>

Inheritance diagram for rgrl_matcher_k_nearest_boundary:

Detailed Description

For each "from" feature, match the boundary points with the k nearest "to" features.

Allows the same operations as for rgrl_matcher_k_nearest. For each center-location match, boundary points are extracted and stored as 2 matches.

FIXME: only deal with 2D for now.
