  • Title: A simple method for fitting sphere-like surfaces.
    Author: Penna MA, Dines KA.
    Journal: IEEE Trans Pattern Anal Mach Intell; 2007 Sep; 29(9):1673-8. PubMed ID: 17627055.
    Abstract:
    In this paper we present a new and simple method for fitting a sphere-like surface to a set of data points in 3-space. In comparison to the standard method that involves using spherical harmonics, this method is conceptually simpler and computationally less complex and intensive, especially when used to address problems in which data is sparse or nonuniform.
