Abstract

We describe a method for automated reading of character strings occurring on scanned topographic maps. This method takes into account the oriented strings that are frequent on maps. We describe the whole application but we emphasize the connected components analysis module and, especially, its rotation-invariant recognition aspect. Results seem good enough for industrial application with our kind of maps (i.e. regular base map for France).
