Occlusion-aware R-CNN: Detecting Pedestrians in a Crowd
This addresses the problem of occluded pedestrian detection for autonomous driving and surveillance systems, representing an incremental improvement over existing methods.
The paper tackles pedestrian detection in crowded scenes by proposing an occlusion-aware R-CNN (OR-CNN) that improves detection accuracy, achieving state-of-the-art results on datasets like CityPersons, ETH, and INRIA.
Pedestrian detection in crowded scenes is a challenging problem since the pedestrians often gather together and occlude each other. In this paper, we propose a new occlusion-aware R-CNN (OR-CNN) to improve the detection accuracy in the crowd. Specifically, we design a new aggregation loss to enforce proposals to be close and locate compactly to the corresponding objects. Meanwhile, we use a new part occlusion-aware region of interest (PORoI) pooling unit to replace the RoI pooling layer in order to integrate the prior structure information of human body with visibility prediction into the network to handle occlusion. Our detector is trained in an end-to-end fashion, which achieves state-of-the-art results on three pedestrian detection datasets, i.e., CityPersons, ETH, and INRIA, and performs on-pair with the state-of-the-arts on Caltech.
