TL;DR

This paper explores the use of Freeman Chain Codes as an alternative method for recognizing Malaysian car plates, aiming to improve accuracy across various font styles and standards.

Contribution

It introduces an experimental approach applying chain codes for car plate recognition, addressing challenges with font variations and non-standard plates in Malaysia.

Findings

Chain codes can effectively recognize different font styles.

The method shows potential for high recognition accuracy.

It offers an alternative to existing recognition techniques.

Abstract

Various applications of car plate recognition systems have been developed using various kinds of methods and techniques by researchers all over the world. The applications developed were only suitable for specific country due to its standard specification endorsed by the transport department of particular countries. The Road Transport Department of Malaysia also has endorsed a specification for car plates that includes the font and size of characters that must be followed by car owners. However, there are cases where this specification is not followed. Several applications have been developed in Malaysia to overcome this problem. However, there is still problem in achieving 100% recognition accuracy. This paper is mainly focused on conducting an experiment using chain codes technique to perform recognition for different types of fonts used in Malaysian car plates.
