| Abstract: | Digital image processing was applied to the recognition system of license plate. In this system, the original image of license plate was firstly transformed, compressed, enhanced and horizontally rectified, then fixed in a position and cut apart by verge exam process. The characteristic extracting and model matching was used in character recognition. Verge exam arithmetic was used to correctly locate license plate and cut apart characters, and every character was recognized accurately and effectively through applying feature value of it. |
