Statistical tests for group comparison of manifold-valued data
Anne Collard, Christophe Phillips, Rodolphe Sepulchre
Motivated by population studies of Diffusion Tensor Imaging, the paper investigates the use of mean-based and dispersion-based permutation tests to define and compute the significa…
An anisotropy preserving metric for DTI processing
Anne Collard, Silvère Bonnabel, Christophe Phillips +1
Statistical analysis of Diffusion Tensor Imaging (DTI) data requires a computational framework that is both numerically tractable (to account for the high dimensional nature of the…
Rank-preserving geometric means of positive semi-definite matrices
Silvere Bonnabel, Anne Collard, Rodolphe Sepulchre
The generalization of the geometric mean of positive scalars to positive definite matrices has attracted considerable attention since the seminal work of Ando. The paper generalize…
