Abstract

A new precision vectorization method has beendeveloped for building centerlines of plain shapes. Firsta dense skeleton is computed. Centerlines are obtained asa subset of branches of the dense skeleton. The denseskeleton can also be used for obtaining medial axes ofshapes. To obtain high precision, the distancetransformation 12-17-38 was developed, which gives agood approximation of the Euclidean metrics. Theexpression the Voronoi L-diagram was coined.
