Abstract :
Car plate recognition is a very important issue in many traffic related applications, and the enhancement process of car plate image is the key step at the very beginning. Its effect relates to the efficiency and precision of car plate localization and recognition directly. This paper brings forward a new car plate image enhancement method based on a simplified PCNN with the parameters determined by images¿ spatial and grey characteristics adaptively. Enhancements on various car plate images are implemented with the proposed algorithm automatically and the experimental results demonstrate its validity and robustness.
