In this paper, we propose a new long video dataset (called Track Long and Prosper - TLP) and benchmark for visual object tracking. The dataset consists of 50 videos from real world scenarios, encompassing a duration of over 400 minutes (676K frames), making it more than 20 folds larger in average duration per sequence and more than 8 folds larger in terms of total covered duration, as compared to existing generic datasets for visual tracking. The proposed dataset paves a way to suitably assess long term tracking performance and possibly train better deep learning architectures (avoiding/reducing augmentation, which may not reflect realistic real world behavior). We benchmark the dataset on 17 state of the art trackers and rank them according to tracking accuracy and run time speeds. We further categorize the test sequences with different attributes and present a thorough quantitative and qualitative evaluation. Our most interesting observations are (a) existing short sequence benchmarks fail to bring out the inherent differences in tracking algorithms which widen up while tracking on long sequences and (b) the accuracy of most trackers abruptly drops on challenging long sequences, suggesting the potential need of research efforts in the direction of long term tracking.

提出了一种名为Track Long and Prosper（TLP）的新型长视频数据集和单个目标跟踪基准，包含50个高清视频，超过400分钟（676K帧），是现有通用数据集平均持续时间的20倍以上，通过对17种现有跟踪器进行精度和运行时间速度排名，以及定性和定量评估，突出了跟踪性能的长期方面的重要性并指出了研究努力在长期跟踪方向的潜在需求。
