Real-time local texture feature target tracking method

Precision and Speed are two conflict indexes in target tracking system. Good feature extracting method is key to precision. Local texture feature has better performance when target rotated or illumination changed. Moreover, its compute time is very short. In order to accelerate tracking algorithm, a new target tracking method is presented by combines the local texture feature and different value pyramid match methods. Experiment results indicate that the precision of this method is more than the traditional methods and the target displacement can be computed less than 20 ms which can meet the requirements of real time target tracking system.
