Project: Time Varying Shape Analysis


 

Statistical Models and Classification of Time-Varying Shape

 

This project investigates new methods for nonlinear statistical analysis and classification of time-varying shape. The challenge in this modeling problem is that shape and shape variations are highly nonlinear and high-dimensional, and standard linear statistics cannot be applied. Therefore, our ability to model and understand changes in shape depends on the development of new regression models for data in nonlinear spaces. The research at the University of Utah develops statistical models for dealing with time-varying shape using least-squares principles in shape manifolds, investigates new classification methods for shape sequences, and validates the proposed methodology using synthetic data and tests its efficacy for neuroimaging applications in Alzheimer's disease and Autism.
