Diffeomorphic shape evolution coupled with a reaction-diffusion PDE on a growth potential
Dai-Ni Hsieh, Sylvain Arguillère, Nicolas Charon +1
This paper studies a longitudinal shape transformation model in which shapes are deformed in response to an internal growth potential that evolves according to an advection reactio…
Mechanistic Modeling of Longitudinal Shape Changes: equations of motion and inverse problems
Dai-Ni Hsieh, Sylvain Arguillère, Nicolas Charon +1
This paper examines a longitudinal shape evolution model in which a 3D volume progresses through a family of elastic equilibria in response to the time-derivative of an internal fo…
A Model for Elastic Evolution on Foliated Shapes
Dai-Ni Hsieh, Sylvain Arguillère, Nicolas Charon +2
We study a shape evolution framework in which the deformation of shapes from time t to t + dt is governed by a regularized anisotropic elasticity model. More precisely, we assume t…
3D Normal Coordinate Systems for Cortical Areas
J. Tilak Ratnanather, Sylvain Arguillère, Kwame S. Kutten +3
A surface-based diffeomorphic algorithm to generate 3D coordinate grids in the cortical ribbon is described. In the grid, normal coordinate lines are generated by the diffeomorphic…
The general setting for Shape Analysis
Sylvain Arguillère
In shape analysis, the concept of shape spaces has always been vague, requiring a case-by-case approach for every new type of shape. In this paper, we give a general definition for…
LDDMM Surface Registration with Atrophy Constraints
Sylvain Arguillère, Michael Miller, Laurent Younes
Diffeomorphic registration using optimal control on the diffeomorphism group and on shape spaces has become widely used since the development of the Large Deformation Diffeomorphic…
