Abstract :
Automatic vectorization of contour lines in topographic maps is one of important and difficult issues for map interpretation and geographic information systems. Based on the analysis of characteristics of contour lines, a novel deformable model for automated tracking is proposed. With the seed segment searching and variable force control, contour lines can be vectorized automatically. The tracking algorithm is significant because it is directed by adaptive flow orientation with global analysis. Experiments prove that it is practical and robust.
