Abstract

The invention discloses a human body behavior action fast recognition method and device. The recognition method includes the steps of extracting contours, acquiring key frames, calculating characteristic operators, setting thresholds and the like, and human body behavior actions are classified according to comparison analysis between the characteristic operators and the thresholds; the recognition device is composed of a movement contour acquiring unit, a behavior model establishing unit and a movement recognition unit. The method and device has the advantages of being simple, efficient, reasonable in use and the like. The matching calculation amount can be reduced, the matching calculation time can be shortened and the real-time performance and the accuracy of behavior action recognition can be improved.

Description

technical field

[0001] The present invention relates to the field of video image processing, in particular to a method and device for human behavior recognition. Background technique

[0002] The purpose of human behavior analysis is to understand and identify individual human actions, interactive movements between people, and interactive relationships between people and the surrounding environment. Behavior recognition has been applied in many fields, such as security systems, medical rehabilitation, and home entertainment. It can use computer technology to realize video-based human detection, human tracking and understanding of human behavior without human intervention or minimal human intervention.

[0003] The traditional human behavior recognition is mainly to detect and track the key parts of the human body and achieve the purpose of recognition. The main method is to attach iconic bright spots to the main joint positions of the subject under test, and identify the s...
