Automatic Recognition and Tracking of Skeletons and Its Application in Automatic Generalization of Contour Lines

This paper is a further research for automatic generalization of contour lines in sets on the basis of reference No.2.In the example of relief generalization by using valley line,the following key points are discussed:The algorithm of selecting skeletons by using distances between valley lines,the approach of modification for the heights of interpolates points,the use of supplemental points in tracking and adjustment of skeletons,etc.
