Abstract

The invention relates to an image processing method and an image processing system for color identification, and a vehicle color identification method and a vehicle color identification system. The image processing method for color identification comprises the following steps: selecting multiple videos from a video acquisition system, selecting a plurality of frames of images from each video, constructing a training set, and identifying a background target codebook of the video acquisition system according to the training set; identifying foreground target pixels corresponding to a target object in a target image according to the background target codebook; eliminating the pixels corresponding to a reflective part of the target object in the foreground target pixels to get body pixels corresponding to a body part; and performing color identification on the target object according to the body pixels to determine the color of the target object. The accuracy of the identified color is improved effectively.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image processing for color recognition, a vehicle color recognition method and system. Background technique [0002] At present, video acquisition systems such as video recording systems that acquire video images of corresponding places at a fixed point have been widely used in people's lives and work. Acquiring and correspondingly processing the video in the above-mentioned video acquisition system, identifying the color of the target object is of great significance to security or related management work; for example, vehicle monitoring video can be obtained in the bayonet system of urban roads or community access control and other places , carry out the color recognition of one of the vehicles, and then determine the identity of the above-mentioned vehicle, which can be used for vehicle retrieval, traffic management and other work. [0003] In the traditional color...
