AbstractThis paper examine the Euler-Lagrange equations for the solution of the large deformation diffeomorphic metric mapping problem studied in Dupuis et al. (1998) and Trouvé (1995) in which two images I0, I1 are given and connected via the diffeomorphic change of coordinates I0○ϕ−1=I1 where ϕ=Φ1 is the end point at t= 1 of curve Φt, t∈[0, 1] satisfying .Φt=vt (Φt), t∈ [0,1] with Φ0=id. The variational problem takes the form $$\mathop {\arg {\text{m}}in}\limits_{\upsilon :\dot \phi _t… 
Morphing of Manifold-Valued Images Inspired by Discrete Geodesics in Image Spaces
It is shown that the continuous manifold-valued functions are dense in $L^2(\Omega,\mathcal{H})$ and a space discrete model based on a finite difference approach on a staggered grid, where the linearized elastic potential in the regularizing term is focused on.

This paper describes a tower of Lie groups which correspond to preserving $k$-th order jet-data and implies the existence of conserved momenta for the reduced system on $T^{\ast}Q^{(k)}$.
Sobolev metrics on shape space of surfaces
Let $M$ and $N$ be connected manifolds without boundary with $\dim(M) < \dim(N)$, and let $M$ compact. Then shape space in this work is either the manifold of submanifolds of $N$ that are
Metric Spaces of Shapes and Geometries Constructed from Set Parametrized Functions
In modelling, optimization, control, or identification problems with respect to a family of subsets of a fixed hold-all in \({\mathbb {R}}^N\), the nice vector space structure of the calculus of
There are several approaches to this question. One is from the perspective of a Riemannian metric on the group of diffeomorphisms of R. If the smooth hypersurfaces Mi bound compact regions Ωi , then
Lorentzian Geodesic Flows and Interpolation between Hypersurfaces in Euclidean Spaces
We consider geodesic flows between hypersurfaces in $\R^n$. However, rather than consider using geodesics in $\R^n$, which are straight lines, we consider an induced flow using geodesics between the
Geometry of diffeomorphism groups and shape matching
The large deformation matching (LDM) framework is a method for registration of images and other data structures, used in computational anatomy. We show how to reformulate the large deformation
A class of fast geodesic shooting algorithms for template matching and its applications via the $N$-particle system of the Euler-Poincar\'e equations
The Euler-Poincar\'e (EP) equations describe the geodesic motion on the diffeomorphism group. For template matching (template deformation), the Euler-Lagrangian equation, arising from minimizing an

A novel framework for computing a path of diffeomorphicisms between a pair of input diffeomorphisms, which compares favorably with the popular Large Deformation Diffeomorphic Metric Mapping framework (LDDMM).

This note gives a partial answer to a question asked during the workshop Mathematics on Shape Spaces. We will denote by Hσ the reproducing kernel Hilbert space of vector fields on R generated by a

Current experimental results from the Toga & Thompson group in growth, the Van Essen group in macaque and human cortex mapping, and the Csernansky group in hippocampus mapping for neuropsychiatric studies in aging and schizophrenia are shown.

Left-invariant metrics are defined on the product G × I thus allowing the generation of transformations of the background geometry as well as the image values, and structural generation in which image values are changed supporting notions such as tissue creation in carrying one image to another.

This paper constructs a distance between deformations defined through a metric given the cost of infinitesimal deformations, and proposes a numerical scheme to solve a variational problem involving this distance and leading to a sub-optimal gradient pattern matching.

The main idea is to consider the objects boundaries in one image as semi-permeable membranes and to let the other image, considered as a deformable grid model, diffuse through these interfaces, by the action of effectors situated within the membranes.
