Abstract(in English) | This paper investigetes the performance of a handwritten character recognition method by hierarchical displacement extraction based on NIST special database (HSF7). The method is composed fo a displacement extraction technique and a coarse-to-fine search strategy. In the displacement extraction technique, the displacement (correspondence) between an input pattern and a prototype is iteratively computed by minimizing a functional defined in the framework of regularization theory. In the coarse-to-fine search strategty, the above-mentioned displacement is determened with multi-resolution images so as to avoid the pitfalls of local minimum and reduce the number of iterations. In addition, a new idea, gradual prototype elimination, is proposed for saving the computation cost without degrading the recognition performance, in which the number of candidate prototypes is eliminated gradually through the hierarchical procedure of the coarse-to-fine search strategy. |
