This document presents a fast algorithm for license plate detection. It begins with an introduction that outlines the need for automatic license plate recognition systems. It then discusses previous work in the area and the challenges involved. The proposed technique is divided into four main parts: histogram equalization, removal of border and background, image segmentation, and license plate detection using feature extraction, principal component analysis, and artificial neural networks. Test results on a dataset of 30 images achieved a 93.33% detection rate. Future work involves implementing the neural network classifier on an FPGA for increased speed.
