org.openimaj.image.feature.local.detector.dog.collector.OctaveMinMaxKeypointCollector

All Implemented Interfaces:

Collector<GaussianOctave<FImage>,MinMaxKeypoint,FImage>, OctaveInterestPointListener<GaussianOctave<FImage>,FImage>

public class OctaveMinMaxKeypointCollector
extends AbstractOctaveLocalFeatureCollector<GaussianOctave<FImage>,GradientFeatureExtractor,MinMaxKeypoint,FImage>

Concrete implementation of an AbstractOctaveLocalFeatureCollector that collects MinMaxKeypoints with the feature vector provided by the given feature extractor. MinMaxKeypoints contain the x, y and scale coordinates of the interest point along with its dominant orientation and a boolean which determines whether the interest point was detected at a local minima or maxima.
