TrackerKCF (AistCV 4.5.3 API)

java.lang.Object
- org.opencv.video.Tracker
- - org.opencv.tracking.TrackerKCF

```
public class TrackerKCF
extends Tracker
```
the KCF (Kernelized Correlation Filter) tracker KCF is a novel tracking framework that utilizes properties of circulant matrix to enhance the processing speed. This tracking method is an implementation of CITE: KCF_ECCV which is extended to KCF with color-names features (CITE: KCF_CN). The original paper of KCF is available at <http://www.robots.ox.ac.uk/~joao/publications/henriques_tpami2015.pdf> as well as the matlab implementation. For more information about KCF with color-names features, please refer to <http://www.cvl.isy.liu.se/research/objrec/visualtracking/colvistrack/index.html>.
