Perturbation of Fiedler vector: interest for graph measures and shape analysis
Julien Lefevre, Justine Fraize, David Germanaud
In this paper we investigate some properties of the Fiedler vector, the so-called first non-trivial eigenvector of the Laplacian matrix of a graph. There are important results abou…
Comparing vector fields across surfaces: interest for characterizing the orientations of cortical folds
Amine Bohi, Guillaume Auzias, Julien Lefèvre
Vectors fields defined on surfaces constitute relevant and useful representations but are rarely used. One reason might be that comparing vector fields across two surfaces of the s…
On early brain folding patterns using biomechanical growth modeling
Xiaoyu Wang, Amine Bohi, Mariam Al Harrach +3
Abnormal cortical folding patterns may be related to neurodevelopmental disorders such as lissencephaly and polymicrogyria. In this context, computational modeling is a powerful to…
Global Perturbation of Initial Geometry in a Biomechanical Model of Cortical Morphogenesis
Amine Bohi, Xiaoyu Wang, Mariam Al Harrach +3
Cortical folding pattern is a main characteristic of the geometry of the human brain which is formed by gyri (ridges) and sulci (grooves). Several biological hypotheses have sugges…
