Automated segmentation of knee bone and cartilage combining statistical shape knowledge and convolutional neural networks: Data from the Osteoarthritis Initiative

F Ambellan, A Tack, M Ehlke, S Zachow - Medical image analysis, 2019 - Elsevier
We present a method for the automated segmentation of knee bones and cartilage from
magnetic resonance imaging (MRI) that combines a priori knowledge of anatomical shape with …

VerSe: a vertebrae labelling and segmentation benchmark for multi-detector CT images

…, Y Hu, T Wang, D Yang, D Xu, F Ambellan… - Medical image …, 2021 - Elsevier
Vertebral labelling and segmentation are two fundamental tasks in an automated spine
processing pipeline. Reliable and accurate processing of spine images is expected to benefit …

[BOEK][B] Statistical shape models: understanding and mastering variation in anatomy

In our chapter we are describing how to reconstruct three-dimensional anatomy from medical
image data and how to build Statistical 3D Shape Models out of many such reconstructions …

An efficient Riemannian statistical shape model using differential coordinates: with application to the classification of data from the osteoarthritis initiative

C von Tycowicz, F Ambellan, A Mukhopadhyay… - Medical image …, 2018 - Elsevier
We propose a novel Riemannian framework for statistical analysis of shapes that is able to
account for the nonlinearity in shape variation. By adopting a physical perspective, we …

Landmark-free statistical shape modeling via neural flow deformations

D Lüdke, T Amiranashvili, F Ambellan, I Ezhov… - … Conference on Medical …, 2022 - Springer
Statistical shape modeling aims at capturing shape variations of an anatomical structure that
occur within a given population. Shape models are employed in many tasks, such as shape …

Verse: a vertebrae labelling and segmentation benchmark

…, Y Hu, T Wang, D Yang, D Xu, F Ambellan… - 2020 - graz.elsevierpure.com
In this paper we report the challenge set-up and results of the Large Scale Vertebrae
Segmentation Challenge (VerSe) organized in conjunction with the MICCAI 2019. The challenge …

Rigid motion invariant statistical shape modeling based on discrete fundamental forms: Data from the osteoarthritis initiative and the Alzheimer's disease …

F Ambellan, S Zachow, C von Tycowicz - Medical Image Analysis, 2021 - Elsevier
We present a novel approach for nonlinear statistical shape modeling that is invariant under
Euclidean motion and thus alignment-free. By analyzing metric distortion and curvature of …

SHREC 2022 track on online detection of heterogeneous gestures

…, MQ Le, HD Nguyen, MT Tran, F Ambellan… - Computers & …, 2022 - Elsevier
This paper presents the outcomes of a contest organized to evaluate methods for the online
recognition of heterogeneous gestures from sequences of 3D hand poses. The task is the …

Towards novel osteoarthritis biomarkers: Multi-criteria evaluation of 46,996 segmented knee MRI data from the Osteoarthritis Initiative

A Tack, F Ambellan, S Zachow - PloS one, 2021 - journals.plos.org
Convolutional neural networks (CNNs) are the state-of-the-art for automated assessment of
knee osteoarthritis (KOA) from medical image data. However, these methods lack …

Sasaki metric for spline models of manifold-valued trajectories

E Nava-Yazdani, F Ambellan, M Hanik… - … Aided Geometric Design, 2023 - Elsevier
We propose a generic spatiotemporal framework to analyze manifold-valued measurements,
which allows for employing an intrinsic and computationally efficient Riemannian …
