A log-euclidean framework for statistics on diffeomorphisms
TL;DR: This article focuses on the computation of statistics of invertible geometrical deformations (i.e., diffeomorphisms), based on the generalization to this type of data of the notion of principal logarithm, which is a simple 3D vector field and well-defined for diffe morphisms close enough to the identity.

TL;DR: A quantitative evaluation comparing the consistency of the two raters as well as exploring the performance of the eleven submitted results in addition to three other lesion segmentation algorithms are presented.
Journal ArticleDOI
Evaluation of an atlas-based automatic segmentation software for the delineation of brain organs at risk in a radiation therapy clinical context
A. Isambert,Frédéric Dhermain,François Bidault,Olivier Commowick,Pierre-Yves Bondiau,Grégoire Malandain,Dimitri Lefkopoulos +6 more
TL;DR: These tests demonstrated that this ABAS is a robust and reliable tool for automatic delineation of large structures under clinical conditions in the authors' daily practice, even though the small structures must continue to be delineated manually by an expert.
