Class TldDetection<T extends boofcv.struct.image.ImageGray<T>>

java.lang.Object

boofcv.alg.tracker.tld.TldDetection<T>

public class TldDetection<T extends boofcv.struct.image.ImageGray<T>>
extends java.lang.Object

Runs a detection cascade for each region. The cascade is composed of a variance test, Fern classifier, and finally the template classifier. The next test in the cascade is only considered if the previous passes. Several changes have been made in how the cascade operates compared to the original paper. See code for comments.
