Spherical Authalic Energy Minimization for Area-Preserving Parameterization

Shu-Yung Liu, Mei-Heng Yueh

Abstract: We propose a new effective method called spherical authalic energy minimization (SAEM) for computing spherical area-preserving parameterizations of genus-zero surfaces. The proposed SAEM has solid theoretical support and guaranteed convergence. In addition, we develop a Riemannian bijective correction method to ensure the bijectivity of the produced mapping under mild assumptions. Numerical experiments showed that the SAEM effectively minimized area distortion with improved bijectivity compared to other state-of-the-art methods.
