Problems solved by technology

For example, existing technologies cannot directly separate different targets, and multiple targets may be detected as a single target, or a single target may be segmented into multiple targets, etc.
In addition, due to the need for global search in the image, the existing technology usually has high computational complexity and long calculation time, which often fails to meet the real-time requirements of practical applications.

Embodiment Construction

[0025] The present invention will be further described below in conjunction with accompanying drawing:

[0026] Such as figure 1 In the schematic diagram of the overall flow chart of the method of the present invention shown, the method for fast recognition of human behavior actions according to the present invention is carried out according to the following steps:

[0027] (1) Gather the video of human behavior action by video acquisition unit, utilize background subtraction method to detect motion and extract human body silhouette and expression thereof; Described background subtraction method is to carry out background subtraction operation in R, G, B spatial distribution to detect motion , set the threshold value to 80 in the R, G, and B3 channels of the image, if the value of any channel is greater than the threshold value, set the value of all channels to 255; otherwise, if the actual pixel value of no channel is greater than The threshold value remains the same;

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...
