In a former work, we built a VLP (Vehicle License Plates) reader using computer vision. To test other methods, we decided to implement a whole new system from scratch. In this communication, we summarize the methods that we have tested and the results we have obtained. Plate location is based on mathematical morphology and character recognition is(More)
In this paper a method to automatically generate a Gaussian mixture classi"er is presented. The growing process is based on the iterative addition of Gaussian nodes. Each iteration takes place in two sequential steps: "rst, using the EM algorithm, we maximize the likelihood of the data under the current con"guration of the classi"er; then, a new Gaussian(More)

This paper presents a novel architecture based on a constructive algorithm that allows the network to grow attending to both supervised and unsupervised criteria. The main goal is to end up with a set of discriminant functions able to solve a multi-class classification problem. The main difference with well-known NN-classificators lean on the fact that(More)
