The Technology Research on Character Segmentation in License Plate Recognition System
License plate recognition is a key process in intelligent transportation system,and characters segmentation of license plate is an important part of vehicle license recognition.According to the projection method and the connectivity method,the prior knowledge of license and the connectivity feature are used with projection curve of license to determine character segment.The characters are segmented by use of the whole properties of license plate characters in height,center coordinate and the special proportion relation between the center intervals between two adjacent characters.Experiments show that the algorithm is simple,the segmentation process is of high quality and efficiency,and good for character recognition.Thus correct character recognition is ensured.
