Abstract
In this paper, we describe an automatic region labeling method, which identifies each region and recognizes region names. Before tracing the region boundaries, it extracts the region names which consist of characters, dots, dashes, and indication lines. It uses two recognition methods to recognize characters in the region name. In the case of recognizing the isolated characters, it uses the open and close features. The characters touching boundaries are recognized by template matching. After removing the components of region names from a map image, the boundaries of each region are extracted. After which it then vectorizes the region boundaries. From these recognition results, the original map can be constructed. It reduces the storage to one fifth of the original data. The proposed method shows 95% accuracy of region labeling.
