Abstract

This paper describes a method that extracts the region of car-licence plates in color images of private and commercial cars. To extract car-licence plates, we use the feature that car-licence plate regions have regular colors according to the kinds of cars. In this paper, we propose the method that combines H component of HSI color model and Q component of YIQ color model. To improve efficiency of the process, we explore lines in a car image by a regular interval in a bottom-up style. As a result, the extraction rates by only H-component, only by Q-component, and by combined H and Q, are 53.6%, 82.1%, and 94.6% respectively.
