Geodesic squared exponential kernel for non-rigid shape registration
Florent Jousse, Xavier Pennec, Hervé Delingette +1
This work addresses the problem of non-rigid registration of 3D scans, which is at the core of shape modeling techniques. Firstly, we propose a new kernel based on geodesic distanc…
Cardiac Motion Modeling with Parallel Transport and Shape Splines
Nicolas Guigui, Pamela Moceri, Maxime Sermesant +1
In cases of pressure or volume overload, probing cardiac function may be difficult because of the interactions between shape and deformations.In this work, we use the LDDMM framewo…
Automatically Segmenting the Left Atrium from Cardiac Images Using Successive 3D U-Nets and a Contour Loss
Shuman Jia, Antoine Despinasse, Zihao Wang +5
Radiological imaging offers effective measurement of anatomy, which is useful in disease diagnosis and assessment. Previous study has shown that the left atrial wall remodeling can…
Template shape estimation: correcting an asymptotic bias
Nina Miolane, Susan Holmes, Xavier Pennec
We use tools from geometric statistics to analyze the usual estimation procedure of a template shape. This applies to shapes from landmarks, curves, surfaces, images etc. We demons…
Higher-Order Momentum Distributions and Locally Affine LDDMM Registration
Stefan Sommer, Mads Nielsen, Sune Darkner +1
To achieve sparse parametrizations that allows intuitive analysis, we aim to represent deformation with a basis containing interpretable elements, and we wish to use elements that…
