Abstract: A collaborative distance metric leaning method and apparatus for visual tracking utilizes a distance metric to match the target with the best candidate. A collaborative distance metric learning algorithm is used for visual tracking by fusing two distance metrics learnt for different representations of the target. To further improve the performance of the trained distance metrics, a sample selection mechanism is also used that exploits the intrinsic structure of dense sampling.
