Abstract
Vehicle tracking based on surveillance videos is of great significance in the highway traffic monitoring field. In real-world vehicle-tracking applications, partial occlusion and objects with similarly appearing distractors pose significant challenges. For addressing the above issues, we propose a robust multivehicle tracking with Wasserstein association metric (MTWAM) method. In MTWAM, we analyze the advantage of the 1-Wasserstein distance (WD-1) on partial occlusion and employ the WD-1 as the similarity criterion to measure the similarity between tracklets and detections. Moreover, for distinguishing different objects with a similar appearance, we improve the feature presentation of vehicles by developing target-specific feature sparse coding (TSSC). To demonstrate the validity of this method, we present a quantitative evaluation of both the UA-DETRAC dataset and our vehicle highway surveillance videos dataset (VecHSV). In both cases, our method achieves state-of-the-art performances.
Highlights
Monitoring systems play an important role in the daily management of highways
Based on the above analysis, we propose a two-stage multivehicle tracking with Wasserstein association metric (MTWAM) method to track vehicles in highway surveillance videos
The contributions of this paper are as follows: 1) We propose a novel vehicle-tracking method called MTWAM for surveillance videos, which combines rich semantic and fine-grained features that are robust against appearance changes and possess sufficient discriminative power for similarity distractors
Summary
Vehicle tracking based on surveillance videos, for which the goal is to provide a continuous trajectory to each target, is the main component of a monitoring system [1]–[4]. Gies, such as the Kalman filter [6]–[8] and the particle filter [9]–[11] These approaches must assume a dynamic model a priori and have trouble distinguishing objects close to other targets. The vast majority of recent methods are based on the tracking-by-detection approach, which builds trajectories via associated detections. These methods typically consist of the following components: a detection method and detection association method based on a similarity measure.
