boofcv.alg.tracker.dda.DetectDescribeAssociateTracker<I,TD>

public class DetectDescribeAssociateTracker<I extends ImageGray<I>,TD extends TupleDesc<TD>>
extends Object

Base class for detect-describe-associate type trackers. Tracker works by detecting features in each image, computing a descriptor for each feature, then associating the features together.
