Describing the application of statistical shape modelling to DXA images to quantify the shape of the proximal femur at ages 14 and 18 years in the Avon Longitudinal Study of Parents and Children [version 2; peer review: 2 approved] [PDF]
Wellcome Open Research, 2019 Bones are complex objects with considerable variation in the shape and structure often attributed to anatomical, environmental or genetic differences.

Landmark-free statistical shape modelling reveals effects of age and sex on whole muscle morphology among the triceps surae [PDF]
Royal Society Open ScienceThe shape of skeletal muscle has important influences on muscle function, yet studies of three-dimensional shape variation are rarely performed. Analysis of muscle shape variation using traditional tools is limited by lack of anatomical landmarks, but ...

Pedigree Aerodynamic Shape Design of High-Speed Trains [PDF]
Journal of Applied Fluid Mechanics, 2022 The aerodynamic performance of high-speed trains is closely related to their head shape. As each train set has its own modelling system, the aerodynamic shape design of head type of a high-speed train must follow a pedigree modelling approach.

Progressive shape models [PDF]
2012 IEEE Conference on Computer Vision and Pattern Recognition, 2012 Dans cet article nous nous concentrons sur un problème récurrent des systèmes d'acquisition 4D : l'apprentissage de la géométrie et de la topologie d'une scène déformable à partir d'une séquence temporelle de maillages. Il s'agit d'une étape fondamentale dans le traitement de scènes naturelles et dynamiques. Tandis que de nombreux travaux ont été menés

Approaches to modelling the shape of nanocrystals
Nano Convergence, 2021 Unlike in the bulk, at the nanoscale shape dictates properties. The imperative to understand and predict nanocrystal shape led to the development, over several decades, of a large number of mathematical models and, later, their software implementations ...

Active Shape Models and the Shape Approximation Problem. [PDF]
Procedings of the British Machine Vision Conference 1995, 1995 Active Shape Models (ASM) use an iterative algorithm to match statistically defined models of known but variable objects to instances in images. Each iteration of ASM search involves two steps: image data interrogation and shape approximation. Here we consider the shape approximation step in detail.

Development of Bead Modelling for Distortion Analysis Induced by Wire Arc Additive Manufacturing using FEM and Experiment [PDF]
MATEC Web of Conferences, 2019 In this research, Wire Arc Additive Manufacturing is modelled and simulated to determine the most suitable bead modelling strategy. This analysis is aimed to predict distortion by means of thermomechanical Finite Element Method (FEM).

Shape modeling with spline partitions
Statistics and Computing, 2022 Shape modelling (with methods that output shapes) is a new and important task in Bayesian nonparametrics and bioinformatics. In this work, we focus on Bayesian nonparametric methods for capturing shapes by partitioning a space using curves. In related work, the classical Mondrian process is used to partition spaces recursively with axis-aligned cuts ...
