Abstract: We propose a deep-learning approach for people detection on depth imagery. The approach is designed to be deployed as an autonomous appliance for identifying people attacks and intrusion in video surveillance scenarios. To this end, we propose a fully-convolutional and sequential network, named WatchNet, that localizes people in depth images by predicting human body landmarks such as head and shoulders. We use a large synthetic dataset to train the network with abundant data and generate automatic annotations. Adaptation to real data is performed via fine tuning with real depth images. The proposed method is validated in a novel and challenging database with about 29k top view images collected from several sequences including different people assaults. A comparative evaluation is given between our approach and other standard methods, showing remarkable detection results and efficiency. The network runs in 10 and 28 FPS using CPU and GPU, respectively.
