Class AbstractOctaveLocalFeatureCollector<OCTAVE extends Octave<?,?,IMAGE>,EXTRACTOR extends FeatureVectorExtractor<?,ScaleSpaceImageExtractorProperties<IMAGE>>,FEATURE extends LocalFeature<?,?>,IMAGE extends Image<?,IMAGE> & SinglebandImageProcessor.Processable<Float,FImage,IMAGE>>

java.lang.Object

org.openimaj.image.feature.local.detector.dog.collector.AbstractOctaveLocalFeatureCollector<OCTAVE,EXTRACTOR,FEATURE,IMAGE>

Type Parameters:

OCTAVE - the type of Octave from which features are extracted

EXTRACTOR - the type of FeatureVectorExtractor which extracts the feature vectors

FEATURE - the type of LocalFeature which are extracted

IMAGE - the type of Image from which features are extracted

All Implemented Interfaces:

Collector<OCTAVE,FEATURE,IMAGE>, OctaveInterestPointListener<OCTAVE,IMAGE>

Direct Known Subclasses:

ConcreteOctaveLocalFeatureCollector, OctaveKeypointCollector, OctaveMinMaxKeypointCollector

extends Object
implements Collector<OCTAVE,FEATURE,IMAGE>

Abstract base class for objects that collate LocalFeatures as they are extracted from Octaves. This base class holds a generic list for storing the features and a reference to the feature extractor instance that is responsible for extracting the feature vectors. Typically the same AbstractOctaveLocalFeatureCollector will be used across all Octaves, and will thus contain all the features from the image.
