Automated Number Plate Recognition Using Hough Lines and Template Matching

Automatic number plate recognition (ANPR) is an image processing technique used to identify the vehicle and its owner by its license plate. This technology is used as a method of electronic toll collection on pay-per-use, by various law enforcing agencies and monitoring traffic activity such as red light adherence in an intersection. This paper presents a robust method of license plate detection and recognition based on Hough lines using Hough transformation and template matching for Islamabad standardized number plates cars. The proposed ANPR technique consists of two main modules: (I) License plate detection module using Canny detector & Hough transformation. (H) License number recognition module using template matching. Experiments have been conducted on 102 samples on Islamabad standardized number plate cars images. These images were taken from different scenes under various illumination conditions.
