Justification of a type of fast anisotropic boundary tracker for multidimensional binary images
T. Yung Kong · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1993
Gordon and Udupa published a fast boundary-tracking algorithm for 3-dimensional finite binary images and confirmed the soundness of their algorithm by observation of its behavior on numerous experimental images. Higher-dimensional analogs of Gordon and Udupa's algorithm are now being used in medical imaging software. This paper presents a proof that these higher-dimensional boundary-tracking algorithms are also sound.
