Elastic matching is one of the promising tequniques for handwritten character recognition. In this tequnique, an input pattern is nonlinearly fitted to a refrence pattern while minimizing their distance as possible. Analytical two-dimensional DP Matching is a novel elastic image matching method to reduce the computations drastically. This method employs a parametric representation of local matching evaluation. This parametric representaiton allows to introduce an analytical optimization process into the DP framework and realizes drastic reduction of computations. In this paper, we evaluate the performance of this method in handwritten digit recognition.
