Title Research on Long-term Tracking Based on Correlation Filter

Abstract：This paper is mainly about the implementation of a long-term tracking algorithm based on correlation filters, which has strong robustness and high execution efficiency. It’s tracking task is decomposed into the estimation both of translation and scale change. Also, it has a supplementary re-test module. This paper first introduced the most popular tracking algorithms based on correlation filters, and elaborates the principle of some trackers. Then ,the paper focuses on the principles and framework of the long-term tracking algorithm based on correlation filters, including training two different regression models based on correlation filters from one image frame, in which the translation is estimated by using the temporal context correlation, the scale estimation is estimated by discriminant correlation filters. After this, this algorithm is tested by running on a standard data

set, with the current most advanced trackers to compare. In addition, it also implements an interactive application and can be used for real-time video tracking. Finally, this paper talks about some problems of long-term correlation trackers that need to be solved and its future trends.
