利用欧氏距离计算三维模型的中轴，希望对大家有用！-Medial Axis (MA), also known as Centres of Maximal Disks, is a useful representation of a shape for image descr iption and analysis.

MA can be computed on a distance transform, where each point is labelled to its distance to the background. Recent algorithms allow one to

compute Squared Euclidean Distance Transform (SEDT) in linear time in any dimension
