Violent interaction detection is a hot topic in computer vision.However, the recent research works on violent interaction detection mainly focus on the traditional hand-craft features, and does not make full use of the research results of deep learning in computer vision.In this paper, we propose a new robust violent interaction detection framework based on multi-stream deep learning in surveillance scene.The proposed approach enhances the recognition performance of violent action in video by fusing three different streams: attention-based spatial RGB stream, temporal stream, and local spatial kangertech subvod leaking stream.

The attention-based spatial RGB stream learns the spatial attention regions of persons that have high probability to quadruple ointment be action region through soft-attention mechanism.The temporal stream employs optical flow as input to extract temporal features.The local spatial stream learns spatial local features using block images as input.Experimental results demonstrate the effectiveness and reliability of the proposed method on three violent interactive datasets: hockey fights, movies, violent interaction.

We also verify the proposed method on our own elevator surveillance video dataset and the performance of the proposed method is satisfied.
