Abstract:
In recent years, many researches on Intelligent
Transportation Systems (ITS) have been reported.
Automatic License Plate Recognition (ALPR) is one
form of ITS technology that not only recognizes and
counts vehicles, but distinguishes each as unique by
recognizing and recording the license plate's
characters. This paper discusses the main techniques of
ALPR. Several open problems are proposed at the end
of the paper for future research.
