CONF Berclaz_PETS_2009/IDIAP Evaluation of Probabilistic Occupancy Map People Detection for Surveillance Systems Berclaz, Jerome Shahrokni, Ali Fleuret, Francois Ferryman, James Fua, Pascal Proceedings of the IEEE International Workshop on Performance Evaluation of Tracking and Surveillance 2009 In this paper, we evaluate the Probabilistic Occupancy Map (POM) pedestrian detection algorithm on the PETS 2009 benchmark dataset. POM is a multi-camera generative detection method, which estimates ground plane occupancy from multiple background subtraction views. Occupancy probabilities are iteratively estimated by fitting a synthetic model of the background subtraction to the binary foreground motion. Furthermore, we test the integration of this algorithm into a larger framework designed for understanding human activities in real environments. We demonstrate accurate detection and localization on the PETS dataset, despite suboptimal calibration and foreground motion segmentation input.
