Shrnutí:The ability to instantly detect risky behavior in video surveillance systems is a critical issue in a smart surveillance system. In this paper, a unified framework based on a deep convolutional framework is proposed to detect abnormal human behavior from a standard RGB image. The objective of the unified structure is to improve detection speed while maintaining recognition accuracy. The deep convolutional framework consists of (1) a human subject detection and discrimination module that is proposed to solve the problem of separating object entities, in contrast to previous object detection algorithms, (2) a posture classification module to extract spatial features of abnormal behavior, and (3) an abnormal behavior detection module based on long short-term memory (LSTM). Experiments on a benchmark dataset evaluate the potential of the proposed method in the context of smart surveillance. The results indicate that the proposed method provides satisfactory performance in detecting abnormal behavior in a real-world scenario. •We propose a method for discriminating objects within a same category by using deep learning based object detection algorithm and Kalman filter.•We propose a deep convolutional framework for extracting dynamic feature of human behavior from standard RGB image.•We model the behavior goal estimation process using a long-short term memory.•We evaluate the method for simple and complex behaviors with goal-directed objects.
