Embodiment Construction

[0022] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0023] see figure 1 , the steps in the embodiment include:

[0024] S11: Detect the outline of the human body in each frame of image;

[0025] S12: It is determined that the distance between any two human body contours in the image is smaller than the first threshold, then respectively detect the skin color of each person's face in the image;

[0026] The first threshold can be set according to the number of pixels. It can also be determined according to the ratio, for example: the distance is 1.3-1.7 times the width of the smallest rectangle that frames the outline of the human body

[0027] S13: If the facial skin color of one of the persons is bruised or reddish purple, and the area is not smaller than the second threshold, it is determined that a fighting behavior occurs.

[0028] In the method in the embodiment, the fighting...

Abstract

The invention provides a method for detecting a fighting behavior based on face identification. The method comprises the following steps of detecting a human body outline in each frame image; when determining that the distance between any two human body outlines in images is less than a threshold value, respectively detecting the skin color of each face in the images; and if the face skin color of one person is bruised or purple and the bruised or purple area is not less than a threshold value, determining that the fighting behavior exists. A fighting process is determined according to the distance between any two human body outlines and the skin color of the faces of human bodies without detecting by the eyes of a user, so that the phenomenon that fighting cannot be timely known is reduced.

Description

technical field [0001] The invention relates to the security field, in particular to a method for detecting fighting behavior based on facial recognition. Background technique [0002] At present, in the field of security protection, events in the current area are detected by cameras, for example, moving people or animals in the current area are detected. [0003] The existing detection technology can only capture the content of the image, and cannot further analyze the content of the image. When there are people fighting in the image, the user can only determine it by observing and judging with his eyes. If he did not see it at that time, these behaviors will be ignored. Contents of the invention [0004] The present invention aims to provide a method for detecting fighting behavior based on facial recognition, so as to solve the problem that the fighting phenomenon in the above images is ignored. [0005] In an embodiment of the present invention, a method for detectin...
