Pedestrian detection method with integration of time domain information and spatial domain information

Abstract

The invention discloses a pedestrian detection method with integration of time domain information and spatial domain information. The pedestrian detection method comprises the steps that (1) pedestrian images are acquired in real time in a specific scene; (2) background modeling is performed by adopting a Gaussian mixture model according to the acquired images, and pedestrian movement foregrounds are detected; (3) spatial domain HOG characteristics, time domain HOG characteristics, spatial domain LBP characteristics and time domain LBP characteristics of pedestrian characteristics are respectively extracted according to the detected movement foregrounds; and (4) classification and discrimination are performed on the pedestrian characteristics by utilizing a random forest classifier according to the characteristics extracted in the step (3) and then results are outputted. The pedestrian detection method is reasonable in design and concise in flow, and a mode of integration of the time domain information and the spatial domain information in the pedestrian detection mode is applied so that accuracy of pedestrian movement detection of the specific scene is greatly enhanced, early-warning capacity of the specific scene is effectively enhanced, and then important guarantee is provided for taking timely preventive measures for the related monitoring personnel.

Description

technical field [0001] The invention relates to a detection method, which belongs to the technical field of image processing, in particular to a pedestrian detection method which combines time domain information and air domain information. Background technique [0002] In recent years, pedestrian detection has attracted more and more people's attention. For example, in the public security video surveillance system, early warning is given to suspicious characters appearing in the scene, so as to prevent crimes and mass incidents and ensure the safety of people's lives and property ; Another example, in supermarkets, shopping centers and other commercial activities, through the detection and tracking of pedestrians appearing in the surveillance video, functions such as passenger flow statistics, crowd density analysis, and passenger flow distribution density can be realized; another example, in large-scale exhibitions and In key monitoring areas such as tourist attractions, th...
