Class BasicTwoWayMatcher<T extends LocalFeature<?,?>>

java.lang.Object

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

Type Parameters:

T -

All Implemented Interfaces:

LocalFeatureMatcher<T>

public class BasicTwoWayMatcher<T extends LocalFeature<?,?>>
extends Object
implements LocalFeatureMatcher<T>

Matcher that uses minimum Euclidean distance to find matches. Model and object are compared both ways. Matches that are oneway are rejected, as are one->many matches.
