Abstract

License plate recognition (LPR) is an important technique in automobile management and traffic control. Experiments show that the recognition rate dropped significantly when the illumination on the license plate is nonuniform. In this chapter, we proposed a simple block-based method to resolve the problem. Experiments show that the proposed method is not only fast but also outperforms well-known Otsu as well as state-of-the-art NiBlack and MAT, with recognition rate of 86% for the 100 nonuniformly illuminated license plate test images.
