Double-person interactive behavior recognizing and active role determining method

Abstract

The invention provides a double-person interactive behavior recognizing and active role determining method. Interpersonal communication is essential in daily life, but undoubtedly some abnormal interactive behaviors cause many troubles, and an existing submitted interactive behavior recognizing scheme is overlong in the recognizing time and tedious in method and can not accurately judge dangerous cases. To solve the problems, the double-person interactive behavior recognizing and active role determining method includes the following steps that (1), by adopting an improved pedestrian detection algorithm based on characteristics of a gradient direction histogram (HOG), pedestrians are detected to obtain position information of the pedestrians on an image; (2), tracks of the pedestrians are extracted according to a multi-target tracking method;(3), the interactive behaviors such as meeting each other halfway, walking together, following, pursuing, joining, getting away from each other, encountering and walking together, encountering and pursuing, encountering and getting away, catching up and walking together, catching up and getting away and catching up and surpassing of double persons are recognized; (4) active roles in all the interactive behaviors of the double persons are determined.

Description

technical field [0001] The invention belongs to the aspects of interactive behavior recognition and role determination in video monitoring, in particular to the recognition of two-person interactive behavior and a novel method for determining active roles. Background technique [0002] With the continuous development of society, people's living standards are also constantly improving. Participating in some social activities will undoubtedly make people communicate more closely, but some abnormal interactive behaviors are often troublesome, such as robbery. Can reduce property loss. Therefore, the recognition of interactive behavior is an important part in the field of video surveillance. However, the traditional visual surveillance mainly studies pedestrian detection, event detection, face fingerprint recognition, and the recognition of interactive behavior, especially the recognition of active characters, is less. Determining the active role in the interactive behavior ca...
