Vertical-Edge-Based Number Plate Detection Method

Abstract

In proposed work we present a number plate detection system with our contributions. We propose a new vertical edge detection algorithm based on contrast between gray scale values. Proposed method enhances the speed of the system. Adaptive thresholding is used for the binarization of the image. an unwanted-line elimination algorithm (ULEA) is proposed to enhance the image, and then, the VEDA is applied. Proposed method processes very-low-resolution images taken by camera. The vertical edges have been detected by the VEDA; the desired plate details based on color information are highlighted. After that the candidate region based on statistical and logical operations will be extracted and LP is detected.
