Segmenting Characters of License Plate Based on Digital Morphology

SONG Chen-guang, YE Hai-jian (Computer Science Department, China Agriculture University, Beijing 100083, China)  
There are many useful applications for a LPR (license plate recognition) system. The LPR algorithm consists of three steps: license plate locating, character segmentation and character recognition. Character segmentation is an important step in a LPR system. There are many factors that cause the characters segmentation task difficult, such as image noise, plate frame, rivet, space mark, plate rotation and illumination variance. A new algorithm for character segmentation was presented. The characters were segmented with the method of connect components which based on the digital morphology. At the same time a valuable project for the divided procession of the characters of vehicle license plate was proposed.
