FLASH: Fast Landmark Aligned Spherical Harmonic Parameterization for Genus-0 Closed Brain Surfaces
TL;DR: FLASH is proposed, a fast algorithm to compute the optimized spherical harmonic parameterization with consistent landmark alignment for genus-0 closed brain surfaces with limited bijectivity under large deformations and slow computation.
Journal ArticleDOI
Brain Surface Conformal Parameterization Using Riemann Surface Structure
Yalin Wang,Lok Ming Lui,Xianfeng Gu,Kiralee M. Hayashi,Tony F. Chan,Arthur W. Toga,Paul M. Thompson,Shing-Tung Yau +7 more
TL;DR: A parameterization method based on Riemann surface structure is introduced, which uses a special curvilinear net structure (conformal net) to partition the surface into a set of patches that can each be conformally mapped to a parallelogram.
Journal ArticleDOI
Texture Map and Video Compression Using Beltrami Representation
TL;DR: This work proposes an effective algorithm for compressing surface homeomorphisms using Fourier approximation of the Beltrami representation, a complex-valued function defined on triangular faces of the surface mesh with supreme norm strictly less than 1.
Journal ArticleDOI
Optimization of Surface Registrations Using Beltrami Holomorphic Flow
TL;DR: In this paper, a simple representation of bijective surface maps using Beltrami coefficients (BCs) is proposed, which is a simpler functional space, which captures many essential features of a surface map.
Journal ArticleDOI
Teichmuller Mapping (T-Map) and Its Applications to Landmark Matching Registration
TL;DR: This paper proposes a special class of diffeomorphisms called the Teichmuller mappings (T-Maps), which under suitable conditions on the landmark constraints can be obtained, which minimizes the maximal conformality distortion.
