Statistics on diffeomorphisms via tangent space representations

  title={Statistics on diffeomorphisms via tangent space representations},
  author={Marc Vaillant and M. I. Miller and Laurent Younes and Alain Trouv{\'e}},
In this paper, we present a linear setting for statistical analysis of shape and an optimization approach based on a recent derivation of a conservation of momentum law for the geodesics of diffeomorphic flow. Once a template is fixed, the space of initial momentum becomes an appropriate space for studying shape via geodesic flow since the flow at any point along the geodesic is completely determined by the momentum at the origin through geodesic shooting equations. The space of initial…

A Log-Euclidean Framework for Statistics on Diffeomorphisms
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.
Low-dimensional shape analysis in the space of diffeomorphisms
Abstract Statistical shape analysis via diffeomorphic image registration is challenging due to the high-dimensional and nonlinear nature of the space of diffeomorphisms. In this chapter, we first

The robustness of this algorithm as applied to the workflow of a large neuroanatomical study is demonstrated by comparing to an existing diffeomorphic landmark matching algorithm.
Evolution Equations with Anisotropic Distributions and Diffusion PCA
This paper presents derivations of evolution equations for the family of paths that in the Diffusion PCA framework are used for approximating data likelihood and shows how rank-deficient metrics can be mixed with an underlying Riemannian metric.
Locally Linear Diffeomorphic Metric Embedding (LLDME) for surface-based anatomical shape modeling
Compared with Principal Component Analysis and ISOMAP, LLDME provides the most compact and efficient representation of the age-related hippocampal shapes and reveals the nonlinear relationship of the hippocampal morphometry with age.
Diffeomorphic 3D Image Registration via Geodesic Shooting Using an Efficient Adjoint Calculation
The key contribution of this work is to provide an accurate estimation of the so-called initial momentum, which is a scalar function encoding the optimal deformation between two images through the Hamiltonian equations of geodesics.
Multi-manifold diffeomorphic metric mapping for aligning cortical hemispheric surfaces
A multi-manifold large deformation diffeomorphic metric mapping (MM-LDDMM) algorithm that allows simultaneously carrying the cortical hemispheric surface and its sulcal curves from one to the other through a flow of diffeomorphisms.
Principal Component Based Diffeomorphic Surface Mapping
This new algorithm reduces the complexity of the estimation of diffeomorphic transformations by incorporating a shape prior in which a nonlinear diffeomorph shape space is represented by a linear space of initial momenta of Diffeomorphic geodesic flows from a fixed template.
A Sub-Riemannian Modular Framework for Diffeomorphism-Based Analysis of Shape Ensembles
This work proposes a new mathematical and computational framework, in which velocity fields are constrained to be built through a combination of local deformation modules with few degrees of freedom, and derives a method to estimate a Frechet mean from a series of observat...
Transport of Relational Structures in Groups of Diffeomorphisms
This paper discusses two main options for translating the relative variation of one shape with respect to another in a template centered representation, based on the Riemannian metric and the coadjoint transport.


Geodesic Shooting for Computational Anatomy
It is shown that this momentum can be also used for describing a deformation of given visual structures, like points, contours or images, and that, it has the same dimension as the described object, as a consequence of the normal momentum constraint the authors introduce.
Soliton dynamics in computational anatomy
A recently discovered momentum map for singular solutions of EPDiff yields their canonical Hamiltonian formulation, which provides a complete parameterization of the landmarks by their canonical positions and momenta, suggesting a new dynamical paradigm for CA, as well as new data representation.
