This paper presents a deep neural-network-based hierarchical graphical model for individual and group activity recognition in surveillance scenes. As the first step, deep networks are used to recognize activities of individual people in a scene. Then, a neuralnetwork-based hierarchical graphical model refines the predicted labels for each activity by considering dependencies between different classes. Similar to the inference mechanism in a probabilistic graphical model, the refinement step… CONTINUE READING
