Well-posedness of eight problems of multi-modal statistical image-matching
Multi-Modal Statistical Image-Matching techniques look for a deformation field that minimizes some error criterion between two images. This is achieved by computing a... -

A Variational Approach to Multi-Modal Image Matching
We address the problem of non-parametric multi-modal image matching. We propose a generic framework which relies on a global variational formulation and show its... -

Variational Analysis of Functionals of a Poisson Process
Let $F$ be a functional of a Poisson process whose distribution is determined by the intensity measure $\mu$. Considering the expectation $\E$ as a function on the... -

Climbing on Pyramids
A new approach is proposed for finding the "best cut" in a hierarchy of partitions by energy minimization. Said energy must be "climbing" i.e. it must be... -
3D image analysis with variational methods and wavelets : applications to med...
Medical procedures have become a critical application area that makes substantial use of image processing. Medical image processing tasks mainly deal with image... -
Modeling non-standard retinal in/out function using computer vision variation...
We propose a computational approach using a variational specification of the visual front-end, where ganglion cells with properties of retinal Konio cells (K-cells),... -
A Class of generalized Laplacians on vector bundles devoted to multi-channels...
In the context of fiber bundles theory, there exist some differential operators of order 2 , called generalized Laplacians, acting on sections of vector bundles over... -
