Gaussian Distributions on Lie Groups and Their Application to Statistical Shape Analysis
The Gaussian distribution is the basis for many methods used in the statistical analysis of shape. One such method is principal component analysis, which has proven to be a powerfu...

Shape Modeling and Analysis with Entropy-Based Particle Systems
This paper presents a new method for constructing compact statistical point-based models of ensembles of similar shapes that does not rely on any specific surface parameterization....

Inverse-Consistent Surface Mapping With Laplace-Beltrami Eigen-Features
Abstract. We propose in this work a novel variational method for computing maps between surfaces by combining informative geometric features and regularizing forces including inver...

Use of 3-D cortical morphometry for mapping increased cortical gyrification and complexity in Williams syndrome
In this paper, we describe the use of three different shape measures -- i.e., shape index, curvedness, and L2 norm of mean curvature -- to quantify cortical gyrification and compl...
