Abstract EN
Object tracking based on low-rank sparse learning usually makes the drift phenomenon occur when the target faces severe occlusion and fast motion.
In this paper, we propose a novel tracking algorithm via reverse low-rank sparse learning and fractional-order variation regularization.
Firstly, we utilize convex low-rank constraint to force the appearance similarity of the candidate particles, so as to prune the irrelevant particles.
Secondly, fractional-order variation is introduced to constrain the sparse coefficient difference in the bounded variation space, which allows the difference between consecutive frames to exist, so as to adapt object fast motion.
Meanwhile, fractional-order regularization can restrain severe occlusion by considering more adjacent frames information.
Thirdly, we employ an inverse sparse representation method to model the relationship between target candidates and target template, which can reduce the computation complexity for online tracking.
Finally, an online updating scheme based on alternating iteration is proposed for tracking computation.
Experiments on benchmark sequences show that our algorithm outperforms several state-of-the-art methods, especially exhibiting better adaptability for fast motion and severe occlusion.
