Abstract(in English) | In this paper we evaluate some learning and discrimination methods for discrimination of signboard pictures from viewpoint of use in mobile environment. Fisher's Linear Discriminant (FLD), the subspace method, the projection distance method, the linear vector quantization, the support vector machine (SVM), the naive Bayes (NB) and the k-nearest neighbor method (k-NN), which are major traditional methods, are evaluated from the time for learning and discrimination and the score which corresponds the correct discrimination rate. Our experiments show that scores of the SVM, the projection distance method, the subspace method, the k-NN, the NB and the FLD with the dimension compression in the combination of every two classes are high, and also show that the time for learning and discrimination in k-NN and NB is short. Finally, we conclude that the NB has the advantage of small increase in the discrimination time over increase in the number of registered signboard against the k-NN. |
