Learning distributions of shape trajectories from longitudinal datasets: a hierarchical model on a manifold of diffeomorphisms

no code implementations CVPR 2018 Alexandre Bône, Olivier Colliot, Stanley Durrleman

We propose a method to learn a distribution of shape trajectories from longitudinal data, i. e. the collection of individual objects repeatedly observed at multiple time-points.

Parallel transport in shape analysis: a scalable numerical scheme

no code implementations23 Nov 2017 Maxime Louis, Alexandre Bône, Benjamin Charlier, Stanley Durrleman

The analysis of manifold-valued data requires efficient tools from Riemannian geometry to cope with the computational complexity at stake.

Prediction of the progression of subcortical brain structures in Alzheimer's disease from baseline

no code implementations23 Nov 2017 Alexandre Bône, Maxime Louis, Alexandre Routier, Jorge Samper, Michael Bacci, Benjamin Charlier, Olivier Colliot, Stanley Durrleman

We propose a method to predict the subject-specific longitudinal progression of brain structures extracted from baseline MRI, and evaluate its performance on Alzheimer's disease data.
