Class MultipleMatchesMatcher<T extends Keypoint>

java.lang.Object

org.openimaj.feature.local.matcher.MultipleMatchesMatcher<T>

Type Parameters:

T - Type of Keypoint being matched

All Implemented Interfaces:

LocalFeatureMatcher<T>

public class MultipleMatchesMatcher<T extends Keypoint>
extends Object
implements LocalFeatureMatcher<T>

A LocalFeatureMatcher that only matches points that are self similar with other points. Target points that match have a distance less than a threshold to the query point. The number of points less than the threshold must be greater than the limit to be counted as matches.
