Identification method and device for fighting behavior, storage medium and electronic device

Abstract

The invention discloses a fighting behavior recognition method and device, a storage medium and an electronic device. The method comprises the steps: calculating optical flow data according to a (t-1)-th frame of image and a t-th frame of image in a target video, and determining whether candidate areas of fighting behaviors exist in the t-th frame of image or not through head and shoulder detection tracking data, wherein t is a positive integer greater than 1; under the condition that it is determined that the candidate area exists in the t-th frame of image, inputting the image sequence of the candidate area in the t-th frame of image and the image sequence of the same area of the L frames of images before the t-th frame of image into a target neural network, and outputting a recognitionresult; under the condition that the recognition result determines that the fighting behavior exists in the candidate area, transmitting early warning information, carrying out the pre-detection operation on fighting behaviors in a video, extracting candidate areas, and then carrying out the secondary filtering on the candidate areas to obtain final fighting areas, and feeding back alarm information, so the technical problem of relatively low accuracy of fighting behavior identification in the prior art is solved.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a fighting behavior recognition method and device, a storage medium and an electronic device. Background technique [0002] At present, video surveillance has been widely used in all walks of life in society. With the popularization of video surveillance, it requires more and more manpower. embarrassing situation. Behaviors such as fighting and fighting threaten public safety, which will bring great negative social impact and need to be avoided as much as possible, especially in scenes with relatively high security requirements such as finance and prisons. Therefore, it is possible to intelligently detect and identify the existence of The act of fighting has great significance. [0003] In the prior art, the judgment of the color and area of ​​the facial skin color is used to determine whether there is a fighting behavior. In practical application scenarios such as priso...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the judgment of the color and area of ​​the facial skin color is used to determine whether there is a fighting behavior. In practical application scenarios such as prisons and finance, due to the large range of movement of the fighting target, it is easy to be blocked by other human bodies or objects, making it difficult to detect Facial information causes missed detection, and at the same time, there may not be a face-slapping situation when fighting, which is not realistic

[0004] For the above problems, no effective solution has been proposed
