Multilevel principal components analysis of three-dimensional facial growth in adolescents
Background and objectives The study of age-related facial shape changes across different
populations and sexes requires new multivariate tools to disentangle different sources of …

An exploration of adolescent facial shape changes with age via multilevel partial least squares regression
Abstract Background and Objectives Multilevel statistical models represent the existence of
hierarchies or clustering within populations of subjects (or shapes in this work). This is a …

What's in a smile? Initial analyses of dynamic changes in facial shape and appearance
Single-level principal component analysis (PCA) and multi-level PCA (mPCA) methods are
applied here to a set of (2D frontal) facial images from a group of 80 Finnish subjects (34 …

4D (3D Dynamic) statistical models of conversational expressions and the synthesis of highly-realistic 4D facial expression sequences
J Vandeventer - 2015 - orca.cardiff.ac.uk
In this thesis, a novel approach for modelling 4D (3D Dynamic) conversational interactions
and synthesising highly-realistic expression sequences is described. To achieve these …

4D analysis of facial ageing using dynamic features
Facial ageing analysis based on 4D data (3D plus time) is much more robust to pose
changes and illumination variations than using 2D image and video. The purpose of this …
