    Detecting Vehicle Interactions in Driving Videos via Motion Profiles
    (IEEE, 2020-09) Wang, Zheyuan; Zheng, Jiang Yu; Gao, Zhen; Electrical and Computer Engineering, School of Engineering and Technology
    Identifying interactions of vehicles on the road is important for accident analysis and driving behavior assessment. Our interactions include those with passing/passed, cut-in, crossing, frontal, on-coming, parallel driving vehicles, and ego-vehicle actions to change lane, stop, turn, and speeding. We use visual motion recorded in driving video taken by a dashboard camera to identify such interaction. Motion profiles from videos are filtered at critical positions, which reduces the complexity from object detection, depth sensing, target tracking, and motion estimation. The results are obtained efficiently, and the accuracy is also acceptable. The results can be used in driving video mining, traffic analysis, driver behavior understanding, etc.
