Class LocalFeatureListDataSource<T extends LocalFeature<?,? extends ArrayFeatureVector<F>>,F>

java.lang.Object

org.openimaj.data.AbstractDataSource<DATATYPE>

org.openimaj.data.AbstractMultiListDataSource<F,T>

org.openimaj.feature.local.data.LocalFeatureListDataSource<T,F>

Type Parameters:

T - The type of LocalFeature

F - The type of FeatureVector.

All Implemented Interfaces:

Iterable<F>, DataSource<F>

public class LocalFeatureListDataSource<T extends LocalFeature<?,? extends ArrayFeatureVector<F>>,F>
extends AbstractMultiListDataSource<F,T>

A DataSource for the feature vector of one or more lists of LocalFeatures that use an ArrayFeatureVector for the feature vector. This can be used as a convenience when you want to feed multiple lists of local features to a clustering algorithm.
