System and method for analyzing intelligent behaviors based on scenes and Markov logic network

Abstract

The invention relates to a system and method for analyzing intelligent behaviors based on scenes and the Markov logic network. The system comprises a scene description machine, an action recognizer and a semantic behavior comprehension describer, wherein the scene description machine is used for classifying the scenes where video images are located according to a theme model method, the action recognizer is used for recognizing atomic action of a person in the video images according to a hidden Markov model method on the basis of the video images, the semantic behavior comprehension describer is used for conducting high-level semantic behavior comprehension and interestingness event description according to a Markov logic network method on the basis of scene classification and atomic action recognition. According to the system and method for analyzing the intelligent behaviors based on the scenes and the Markov logic network, scene description is introduced to high-level semantic behaviors of video to be analyzed, so that the video is more thoroughly described; a field rule knowledge base is introduced to the Markov logic network to be improved, so that high-level semantic behavior description and related event description are achieved more flexibly, and a wider application range is achieved.

Description

technical field [0001] The present invention relates to the field of visual analysis and intelligent understanding of human behavior, in particular to the field of visual analysis and intelligent understanding of human behavior based on scene description and Markov logic network, specifically refers to an intelligent behavior analysis based on scene and Markov logic network systems and methods. Background technique [0002] With the development of technology and the gradual reduction of the price of hardware equipment, a large number of surveillance cameras have been installed in various places, especially those places that are sensitive to security requirements, such as airports, communities, banks, parking lots, military bases, etc. Visual monitoring of dynamic scenes is a frontier research direction that has attracted much attention in recent years. It detects, recognizes, tracks targets and understands their behavior from image sequences captured by cameras. Human behav...

Problems solved by technology

However, a very important part of the high-level semantic understanding of human behavior is scene information. None of the above achievements combine behavior recognition and scene analysis, ignoring the impact of interest events generated by human-environment interaction on real life.
