Abstract

The embodiment of the invention relates to a moving object detection method and device based on background subtraction, relates to the technical field of image recognition, and mainly solves the technical problem that the moving object detection effect is poor. The detection method comprises the following steps: constructing a visual extraction background sample model based on a visual backgroundextraction sub-algorithm; constructing an auxiliary background sample model of image pixels according to the image of the video; analyzing the flicker degree of the image pixels of the video between the foreground and the background, and for the flicker pixels with the flicker degree meeting a preset condition, replacing samples corresponding to the positions of the flicker pixels in the auxiliarysample model to generate an image after flicker analysis; classifying foreground pixels and background pixels for the pixels in the flicker-analyzed image according to the visual extraction background sample model, and generating a moving target according to the foreground pixels. Compared with the prior art, the detection of the moving target by the dynamic pixels can be effectively inhibited, and the moving target detection effect is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of image recognition, in particular to a method and device for detecting a moving target based on background subtraction. Background technique [0002] With the development of digital video technology, people can detect, track, identify and analyze moving objects in surveillance video. Using these technologies, people can quickly obtain effective information such as the position, trajectory, and behavior of the moving target that needs to be detected. Moving object detection is the basis of technologies such as moving object tracking, behavior recognition, and scene description, and the detection results directly affect the accuracy of subsequent algorithms. Therefore, how to improve the accuracy and robustness of object detection has become one of the main research directions in the field of computer vision. Currently, moving target detection methods mainly include: frame differe...
