statistical shape analysis
During the course of my PhD research, I have studied and extended the particle correspondence model proposed by Josh Cates toward specific applications.
Geometric Correspondence for Nonregular Surfaces
To resolve the challenges posed by highly nonregular surfaces, we have proposed an efficient method which incorporates Geodesic distances and an intershape penalty based on surface normals to improve correspondences. [ MICCAI 2011 ]
GPU Acceleration for Particle Systems
GPGPU concepts are applied to implement an efficient parallel implementation of the particle distribution process. [ SAAHPC 2010 ]
Linear Regression For Particle Correspondence
Correspondence based on linear regression was incorporated to arrive at a normative model of early head shape development. Other contributions of this work included the ability to deal with open surfaces and permutation tests for significance. [ MICCAI 2009 ]
