Abstract:As a special computer vision system, the License Plate Recognition System (LPR)can capture a vehicle automatically and identify the plate numbers in the image. Contributing a lot to the automation of the transportation managment. In this paper, some methods and algorithms are introduced in such stages as preprocessing of images, license plate location, character segmentation and character recogenition. At the same time, compare the methods with the existing. Moreover, designing and improving parts of critical algorithm. Testing 40 representative vehicle license plates, I can achieve the good accuracy.
Keywords:License plate location  Vertical texture  Character segmentation  Character recognition
