Class OctaveInterestPointFinder<T extends InterestPointData>

java.lang.Object

org.openimaj.image.feature.local.detector.ipd.finder.OctaveInterestPointFinder<T>

Type Parameters:

T - The type of InterestPointData

All Implemented Interfaces:

OctaveProcessor<GaussianOctave<FImage>,FImage>

Direct Known Subclasses:

CharacteristicOctaveInterestPointFinder, LoggingOctaveInterestPointFinder

public class OctaveInterestPointFinder<T extends InterestPointData>
extends Object
implements OctaveProcessor<GaussianOctave<FImage>,FImage>

Finder with a specified detector which finds interest points at a given gaussian octave. This is often used in conjunction with a GaussianPyramid which provides GaussianOctave instances. This finder calls a specified InterestPointFeatureCollector which does something with the features located at a given octave.
