Identifying Blurry Car License Number Plate Using Machine Learning

Abstract

Due to advances of semiconductors, smartphones become common tools and security cameras are filled in downtowns. Smartphone pictures and recorded security camera images sometimes give us important information of crimes. Car license plate numbers are one of them because cars are often used in criminals. However, the recorded images/pictures are blurry and the license plate numbers cannot be readable. Although there is machine learning systems to improve resolution of blur numbers, their performances change depending on classifiers. In this paper, the performances of the classifiers are compared and the best one is reported.
