| contents | Automatic system for localization and recognition of vehicle plate numbers N. Vázquez M. Nakano H. Pérez Meana Ingeniería Number plate Alphabet recognition Identification with neural networks This paper proposes a vehicle numbers plate identification system, which extracts the characters features of aplate from a captured image by a digital camera. Then identify the symbols of the number plate using amultilayer neural network. The proposed recognition system consists of two processes: The training processand the recognition process. During the training process, a database is created using 310 vehicular plateimages. Then using this database a multilayer neural network is trained to identify the symbols in the vehiclesplate. While the recognition process consists of four stages: The number plate localization stage, thebinarization stage, the segmentation stage and the recognition stage which uses the previously trainedmultilayer neural network. The performance of proposed system is evaluated using more than 1200 symbolsfrom the 310 captured images. The simulation results show that approximately 91.5% of the 310 plate imagesin the vehicle have been correctly located. The proposed system performance, regarding the identification ofnumbers and letters in the plate, was evaluated separately. Here the recognition rate is 95.55% and 91.6%,respectively. So the global recognition rate of the vehicle number plate becomes approximately 91.2%. Thenfrom the simulation results it follows that the proposed system works fairly well and then it may be applied inthe solution of several practical problems that require automatic number plate identification. 2003 artículo científico 1665-6423 https://www.redalyc.org/articulo.oa?id=47400106 en http://www.redalyc.org/revista.oa?id=474 Journal of Applied Research and Technology application/pdf Universidad Nacional Autónoma de México Journal of Applied Research and Technology (México) Num.1 Vol.1 |
