Abstract

In this paper, a character recognition experiment using piecewise linear two-dimensional warping, a dynamic programming-based elastic image matching technique, is reported. The present technique requires far less computations than the previous methods, such as monotonic and continuous two-dimensional warping, since line segment is used instead of pixel as the unit of mapping. This consideration does not decrease the recognition accuracy, as shown by the experimental result. Additional results also show the superiority of the present technique over template matching and two-dimensional warping techniques based on combinations of orthogonal one-dimensional warpings.
