java.lang.Object

org.openimaj.image.feature.local.detector.ipd.collector.InterestPointFeatureCollector<T>

Type Parameters:

T - The type of InterestPointData

Direct Known Subclasses:

AffineInterestPointFeatureCollector, CircularInterestPointFeatureCollector

public abstract class InterestPointFeatureCollector<T extends InterestPointData>
extends Object

An interest point feature collector can be used to hold interest points found in an image. Interest point collectors decide what area of the image is considered "interesting" pass this information on to their designated extractor.
