Research on the segmentation of license plate characters

Abstract

A license plate location method based on plate texture and color is introduced. Connected domain method and template matching method are chosen to realize characters segmentation. Firstly, Canny edge detection and dilatation & erosion algorithm referred to morphological image processing are used to fuse the region with the similar texture features, and then color segmentation method is adopted with the fusion images to achieve plate location shearing. Secondly, characters segmentation is implemented with connected domain method. Finally, segmented characters are recognized with the template. Experiments show that the method is simple, easy and effective to carry out plate location and recognition.
