Toponym Recognition in Historical Maps by Gazetteer Alignment [PDF]

2013 12th International Conference on Document Analysis and Recognition, 2013
Historical map documents are increasingly digitized for widespread access, but most are only coarsely indexed with meta-data while the contents are largely unsearchable. We propose to increase search ability by automatically recognizing the place names in these digitized artifacts.

Toponym Recognition in Scanned Color Topographic Maps

Proc Int Conf Doc Anal Recognit, 2007
Topographic paper maps are a common support for geographical information. In the field of document analysis of this kind of support, this paper proposes an automatic approach to extract and recognize toponyms. We present a technique based on image segmentation and connected component processing.
