     * 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>.
