Class FactoryInterestPoint

java.lang.Object

boofcv.factory.feature.detect.interest.FactoryInterestPoint

public class FactoryInterestPoint
extends Object

Factory for creating interest point detectors which conform to the InterestPointDetector interface

NOTE: Higher level interface than GeneralFeatureDetector. This will automatically compute image derivatives across scale space as needed, unlike GeneralFeatureDetector which just detects features at a particular scale and requires image derivatives be passed in.
