However, these methods are complex and inaccurate , and saddle points can hardly be extended to 3D case. In this paper a novel method was presented , the skeleton obtained by growing from the skeleton seed with 1 pixel width restncted by distance transfonn , and the connectivity was assured by the growing process. Expenments show that the growing process is a skeleton evolvement from coarse to delicate , and the hier
