Center node: "roadtrack tracking road agents in dense and heterogeneous environments"
  Abstract: We present an algorithm to track traffic agents in dense videos. Our approach is designed for heterogeneous traffic scenarios that consist of different agents such as pedestrians, two-wheelers, cars, buses etc. sharing the road. We present a novel Heterogeneous Traffic Motion and Interaction model (HTMI) to predict the motion of agents by modeling collision avoidance and interactions between the agents. We implement HTMI within the tracking-by-detection paradigm and use background subtracted representations of traffic agents to extract binary tensors for accurate tracking. We highlight the performance on a dense traffic videos and observe an accuracy of 75.8%. We observe up to 4 times speedup over prior tracking algorithms on standard traffic datasets.
