WebThe medial axis of a solid object is its skeletal surface. The skeleton reduces the dimension of a solid while preserving its basic shape. The medial axis also captures proximity information about opposing points on the solid’s boundary. The medial axis was ﬁrst proposed by Blum [3] for biological shape measurement. http://wwwx.cs.unc.edu/~geom/papers/documents/articles/2003/culver03.pdf dr felix chua royal brompton hospital
