Abstract

The invention discloses a foreground image extraction method, which comprises the steps of processing an original vehicle background model based on a symmetrical background elimination method to obtain a first vehicle background model after an information-free background is extracted; performing image segmentation processing on the first vehicle background model to obtain a foreground image to beprocessed; and performing shadow elimination processing on the foreground image to be processed based on the texture difference in the foreground image to be processed. According to the foreground image extraction method provided by the embodiment of the invention, the accuracy of foreground image extraction is improved through information-free background extraction, image segmentation and shadowelimination, so that the vehicle can be stably and accurately identified.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a foreground image extraction method. Background technique [0002] Nowadays, image processing technology is widely used in the fields of vehicle safety management and road traffic control. Through high-definition video collection and effective detection and identification of vehicle images, it provides visual information reference for drivers and vehicle management and dispatching centers. The optimal management of vehicles has been realized. Background and foreground are two relative concepts in image processing. Through the processing of the background model, the foreground image of the moving vehicle is extracted, which is crucial for post-processing such as object tracking, target classification, and behavior understanding. [0003] However, the existing vehicle foreground image extraction methods do not take into account the interference from noise and shadows in ...
