摘要:

基于相关滤波器(CF)的方法在无人机(UAV)应用中的视觉目标跟踪中表现出优异的性能,但受到不期望的边界效应的影响。为了解决这个问题,空间正则化相关滤波器(SRDCF)提出了空间正则化惩罚滤波器系数,从而显着提高跟踪性能。然而,隐藏在响应地图中的时间信息没有被考虑在SRDCF中,这限制了精确跟踪的区分能力和鲁棒性。本文提出了一种新的动态一致性相关滤波方法,即,CPCF追踪器具体地,通过相邻响应图之间的相关性操作,生成实际的一致性图以表示跨帧的一致性水平。通过最小化实际一致性图与预定理想一致性图之间的差异,约束一致性水平以保持时间平滑性,并在响应图中引入丰富的时间信息.此外,提出了动态约束策略,进一步提高了跟踪器在复杂情况下的适应性。在三个具有挑战性的无人机基准上进行了综合实验,UAV123@10FPS、UAVDT和DTB70。实验结果表明,该跟踪器在单CPU上的实时的【形】运行速度($\sim$ 43 FPS)优于其他25种最先进的跟踪器。

英文摘要:

Correlation filter (CF)-based methods have demonstrated exceptional performance in visual object tracking for unmanned aerial vehicle (UAV) applications, but suffer from the undesirable boundary effect. To solve this issue, spatially regularized correlation filters (SRDCF) proposes the spatial regularization to penalize filter coefficients, thereby significantly improving the tracking performance. However, the temporal information hidden in the response maps is not considered in SRDCF, which limits the discriminative power and the robustness for accurate tracking. This work proposes a novel approach with dynamic consistency pursued correlation filters, i.e., the CPCF tracker. Specifically, through a correlation operation between adjacent response maps, a practical consistency map is generated to represent the consistency level across frames. By minimizing the difference between the practical and the scheduled ideal consistency map, the consistency level is constrained to maintain temporal smoothness, and rich temporal information contained in response maps is introduced. Besides, a dynamic constraint strategy is proposed to further improve the adaptability of the proposed tracker in complex situations. Comprehensive experiments are conducted on three challenging UAV benchmarks, i.e., UAV123@10FPS, UAVDT, and DTB70. Based on the experimental results, the proposed tracker favorably surpasses the other 25 state-of-the-art trackers with real-time running speed ($\sim$43FPS) on a single CPU.
