摘要

Conventional license plate detection methods have a good success rate in detecting one or a few fixed formats, however, they may fail in some cases such as motorcycles in Japan and foreign vehicles across national borders. The authors have developed a novel method to detect different types of license plates. This method employs Bag-of-Features based on Histogram of Oriented Gradients, which enables the detector to identify characters' common curves on different types of plates. Moreover, this method reduces the computation time and false detection as used in combination with screening technology and edge distribution. The experiment results show that the method is effective for detecting motorcycle license plates in Japan.
