摘要：
This paper addresses the problem of contour lines extraction from scanned topographic maps. A novel method called "local window segmentation" is developed and used to overcome the difficulty of the gaps and thick lines. Experiments and evaluations on a number of well- and common-conditioned topographic maps are provided.
