How to Register a Live onto a Liver ? Partial Matching in the Space of Varifolds
Pierre-Louis Antonsanti, Thomas Benseghir, Vincent Jugnon +4
Partial shapes correspondences is a problem that often occurs in computer vision (occlusion, evolution in time...). In medical imaging, data may come from different modalities and…
A deep residual learning implementation of Metamorphosis
Matthis Maillard, Anton François, Joan Glaunès +2
In medical imaging, most of the image registration methods implicitly assume a one-to-one correspondence between the source and target images (i.e., diffeomorphism). However, this…
Metamorphic image registration using a semi-Lagrangian scheme
Anton François, Pietro Gori, Joan Glaunès
In this paper, we propose an implementation of both Large Deformation Diffeomorphic Metric Mapping (LDDMM) and Metamorphosis image registration using a semi-Lagrangian scheme for g…
Partial Matching in the Space of Varifolds
Pierre-Louis Antonsanti, Joan Glaunès, Thomas Benseghir +2
In computer vision and medical imaging, the problem of matching structures finds numerous applications from automatic annotation to data reconstruction. The data however, while cor…
Database Annotation with few Examples: An Atlas-based Framework using Diffeomorphic Registration of 3D Trees
Pierre-Louis Antonsanti, Thomas Benseghir, Vincent Jugnon +1
Automatic annotation of anatomical structures can help simplify workflow during interventions in numerous clinical applications but usually involves a large amount of annotated dat…
Kernel Operations on the GPU, with Autodiff, without Memory Overflows
Benjamin Charlier, Jean Feydy, Joan Alexis Glaunès +2
The KeOps library provides a fast and memory-efficient GPU support for tensors whose entries are given by a mathematical formula, such as kernel and distance matrices. KeOps allevi…
