java.lang.Object

org.openimaj.image.feature.local.detector.dog.collector.AbstractOctaveLocalFeatureCollector<GaussianOctave<IMAGE>,ScaleSpaceFeatureExtractor<OrientedFeatureVector,IMAGE>,Keypoint,IMAGE>

org.openimaj.image.feature.local.detector.dog.collector.OctaveKeypointCollector<IMAGE>

Type Parameters:

IMAGE - Type of underlying Image

All Implemented Interfaces:

Collector<GaussianOctave<IMAGE>,Keypoint,IMAGE>, OctaveInterestPointListener<GaussianOctave<IMAGE>,IMAGE>

public class OctaveKeypointCollector<IMAGE extends Image<?,IMAGE> & SinglebandImageProcessor.Processable<Float,FImage,IMAGE>>
extends AbstractOctaveLocalFeatureCollector<GaussianOctave<IMAGE>,ScaleSpaceFeatureExtractor<OrientedFeatureVector,IMAGE>,Keypoint,IMAGE>

Concrete implementation of an AbstractOctaveLocalFeatureCollector that collects Keypoints with the feature vector provided by the given feature extractor. Keypoints contain the x, y and scale coordinates of the interest point along with its dominant orientation
