Automatic license plate recognition

Abstract

This paper presents an automatic license plate recognition algorithm by using webcam. The images of vehicle license plate, which were captured by using webcam are noised, illuminated and skewed under natural environment. We have to preprocess to get clean binary image and extract each character area to recognize numbers. But they are not simple jobs. In this paper, the high-speed and sophisticated rules for preprocessing and segmenting of plate image are experimented. A new recognition technique is also proposed which has produced the best recognition rate of 98.5% when tested on the images of 120 vehicles by using webcam.
