Multi-scale filter approach segmentation steps are presented by: a) recovery of line structures of various widths, b) Hessian eigenvalues (i.e., linear intensity minima) removal of the effects of non-linear structures and recovery of the original structures as described by Sato et al., [26]c) removal of the effects of non-uniformity of contrast material, noise and artifacts, and d) 3-dimensionality
