Struct TrackerKCF

pub struct TrackerKCF { /* private fields */ }

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 KCF_ECCV which is extended to KCF with color-names features (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.
