The vehicle license plate recognition (VLPR) system analyzes and monitors the speed of vehicles, theft of vehicles, the violation of traffic rules, illegal parking, etc., on the motorway. The VLPR consists of three major parts: license plate detection (LPD), license plate character segmentation (LPCS), and license plate character recognition (LPCR). This paper presents an efficient method for the LPCS and LPCR of Korean vehicle license plates (LPs). LP tilt adjustment is a very important… 

Continuous risk profile and clustering-based method for investigating the effect of the automated enforcement system on urban traffic collisions

It was observed that the severity of collisions was alleviated in most clusters after AES installation, and this may be viewed as a positive effect caused by the decrease in vehicle speed due to speeding enforcement.

Vertical-Edge-Based Car-License-Plate Detection Method

A fast vertical edge detection algorithm (VEDA) based on the contrast between the grayscale values, which enhances the speed of the CLPD method and is compared to the Sobel operator in terms of accuracy, algorithm complexity, and processing time.

A new method for correcting vehicle license plate tilt

The experimental results verify that this proposed method can be easily implemented, and can quickly and accurately get the tilt angle, and provides a new effective way for the VLP image tilt correction.

Variance Window Based Car License Plate Localization

The proposed method is robust enough to locate the plates in cases where the rough vehicle position has not been previously discovered and the cars are not centered in the image.


These methods are explained in this paper and one of them is implemented in C# programming language and the results show that the algorithm works fine in cases without much deformation of an input image.
