Hough Transform and Its Application in Declining License Plate
Liang Yan-hua · Information and Electronic Engineering · 2004
A new usage of Hough Transform is introduced in this paper.Firstly,the position and scope of the license plate is located and the image that contains the license plate is picked up.Then, a two-stage Hough transform algorithm is applied to the image to calculate the angle of the main line.This angle is thought as the declining angle of the license plate.Lastly,the orientated image rectified using interpolation rotation method.This algorithm is validated through simulation tests.
