Here is presented a method for license plates character recognition based on neural networks. In this work, the main objective was to explore the use of simple techniques in the image pre-processing, avoiding the use of complex mathematical models and decreasing computational cost. The idea is that the neural nets will handle the imprecision caused by such poor preprocessing. To accomplish that, it has been used multilayer supervised trained neural nets, followed by external decision layer, which, in identification time, promote competition among neurons in the output layer, allowing activation of only one winner. Preliminary tests reveal the rate of about 93% of correct full plate identifications. Clique no link abaixo para buscar o texto completo deste trabalho na Web: Buscar na Web
