Abstract

Aiming at the problem that single feature cannot effectively model targets and the direct superposition of response channels affect the tracking quality. Based on discriminative scale space tracking(DSST), this paper developed an adaptive model update and response weighted real-time correlation filter tracking algorithm. Firstly, the algorithm integrated multi-dimensional feature, and applied adaptive weighting to every response channel. Secondly, the proposed tracker incorporated the quadratic polynomial fitting strategy to improve the accuracy of scale estimation. Finally, it introduced the model update strategy to improve the reliability of the sample and accelerate the tracker. It performed experiments on OTB2013 and OTB2015. Compared with the baseline tracker, the proposed algorithm improves 6.4% and 6.7% in success. Compared with the recent tracking algorithm, it shows excellent performance, and has a speed of 85 fps, which is three times than that of DSST, and exceeds most real-time tracking algorithms.
