Embodiment Construction

[0022] Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like numerals refer to like parts throughout. The embodiments are described below in order to explain the present invention by referring to the figures.

[0023] figure 1 A flow chart showing a method for detecting pedestrians in video images of scene changes by using multiple detectors according to an exemplary embodiment of the present invention. Here, as an example, the method may be implemented by related video monitoring equipment, or may be entirely implemented by a computer program.

[0024] Such as figure 1 As shown, in step S100, for a plurality of different scenes, the scene background model of each scene is respectively obtained, and the pedestrian detector of each scene is trained respectively.

[0025] Specifically, the video images taken by the monitoring equipment in different scenes can be obtained in ad...

Abstract

Provide a kind of method that utilizes multi-detector to carry out pedestrian detection to the video image of scene change, comprise: (A) for a plurality of different scenes, obtain the scene background model of each scene respectively, and train the pedestrian detection of each scene respectively (B) set up the corresponding relationship set about the scene background model and the pedestrian detector; (C) obtain the video image of the scene change, and divide the video image into a plurality of video segments; (D) for the plurality of video For each video segment in the segment, a segment background model of each video segment is acquired, and a pedestrian detector determined based on the segment background model of each video segment is used to detect pedestrians in each video segment. According to the method, the pedestrian recognition rate when the scene changes can be effectively improved, and the labor cost is reduced.

Description

technical field [0001] The present invention generally relates to the technical fields of computer vision and pattern recognition. More specifically, it relates to a method for pedestrian detection in scene-changing video images using multiple detectors. Background technique [0002] Pedestrian detection is an important research direction in the field of intelligent video surveillance. It is a computer vision technology based on machine learning. and other tasks. [0003] Pedestrians have the characteristics of both rigid and flexible objects, and their appearance is easily affected by clothing, scale, occlusion, posture and viewing angle, which makes pedestrian detection a research difficulty and hotspot in the field of intelligent video surveillance. Pedestrian detection is mainly divided into two steps, first feature extraction, and then classification and positioning. Among them, there are three main types of feature extraction methods: (1) the underlying feature extr...
