Class FactoryDetectPoint

java.lang.Object

boofcv.factory.feature.detect.interest.FactoryDetectPoint

public class FactoryDetectPoint
extends java.lang.Object

Creates instances of GeneralFeatureDetector, which detects the location of point features inside an image.

NOTE: Sometimes the image border is ignored and some times it is not. If feature intensities are not computed along the image border then it will be full of zeros. In that case the ignore border region needs to be increased for non-max suppression or else it might generate a false positive.
