A nonparametric Riemannian framework for processing high angular resolution diffusion images and its applications to ODF-based morphometry

► Present a Riemannian framework to carry out generic computations on an ODF field. ► Does not require that the ODFs be represented by any fixed parameterization. ► Used Riemannian operations to perform various geometric data processing. ► Generalized Hotelling's T2 test for ODF hypothesis testing in population studies. ►Illustrated with experiments including measuring left/right brain asymmetries.
