Package boofcv.abst.feature.detdesc

Class DetectDescribeFusion<T extends ImageGray<T>,TD extends TupleDesc<TD>>

java.lang.Object
boofcv.abst.feature.detdesc.DetectDescribeFusion<T,TD>
All Implemented Interfaces:
DescriptorInfo<TD>, DetectDescribePoint<T,TD>, FeatureSets, FoundPointSO, InterestPointDetector<T>
public class DetectDescribeFusion<T extends ImageGray<T>,TD extends TupleDesc<TD>> extends Object implements DetectDescribePoint<T,TD>
Wrapper class around independent feature detectors, region orientation, and descriptors, that allow them to be used as a single integrated unit. Providing an algorithm for estimating orientation is optional. If one is provided, any orientation estimate provided by the detector is ignored.
