Matlab implementation of our Real-time illuminative adaptive Anti-Dark tracker (ADTrack).
Visual object tracking, which has facilitated numerous applications, is representing a major interest in image signal processing field. Among which, equipping unmanned aerial vehicle (UAV) with all-day real-time robust visual trackers, is currently attracting incremental attention and has remarkably broadened the scope of applications of object tracking. However, prior tracking methods have merely focused on robust tracking in the well-illuminated scenes, while ignoring UAV's satisfying tracking in the dark. In darkness, the conditions can be more complex and harsh, easily leading to inferior robust tracking or even tracking failure. To this end, this work proposed a novel tracker with illumination adaptive and anti-dark capacity (ADTrack), which is based on discriminative correlation filter. ADTrack firstly exploits image illuminance information to enable adaptability to the given light condition. Then, by virtue of an efficient and effective image enhancer, ADTrack carries out image pretreatment, where a target-aware mask is generated. Benefiting from the mask, ADTrack aims to solve a dual regression where dual filters, i.e., the context filter and target-focused filter, are trained with mutual constraint. Thus ADTrack is able to maintain continuously favorable performance in all-day conditions. Besides, this work also constructed the very first UAV nighttime tracking benchmark UAVDark135, comprising of more than 125k manually annotated frames, which is also the biggest UAV tracking benchmark. Exhaustive experiments are extended on authoritative daytime benchmarks, i.e., UAV123@10fps, DTB70, and newly built dark benchmark UAVDark135. Results have validated the superiority of ADTrack in both bright and dark conditions compared with other arts. Meanwhile, ADTrack realizes a real-time speed of over 30 frames/s on a single CPU, greatly promoting UAV's all-day robust tracking.
