3D Facial Imaging and Shape Modelling
Research in the Orthodontics and 3D Imaging Research group uses 3D facial imaging in order to "explain facial variation (biological make-up, anatomy, facial surface morphology and function) to inform a fully functioning biomechanical head model which is of value to improve healthcare interventions, improve wellbeing and quantify facial variation for face-wear, facial identification/forensics and computer interface industries."
My research focusses on developing mathematical models of 3D facial shape in order to achive the aims above. I have developed a multilevel principal components analysis (mPCA) code that allows us to model different sources of variations at different levels of the model. Recent research successes using the mPCA approach via this code have been:
- Detecting changes in facial shapes between different nationalities and also by sex. Click here for more details.
- Identifying seven phases of a "smile" in dynamic 3D shape "video" data. Click here for more details.
- Modelling age-related facial changes in Finnish and Welsh adolescents. Click here for more details.
Automated Retinal Image Analysis (ARIA) dataset
Principal researcher for the ARIA project at St. Paul's Eye Unit, RLUHT. Recruitment of patients, retinal photography, and image analysis of resulting digital fundus photographs. See this link http://eyecharity.weebly.com/aria_online.html for a directory of images collected by members of staff of St Paul's Eye Unit and the University of Liverpool as part of the ARIA project.
CCCM (crystallographic coupled cluster method):
CCCM is a high-order CCM (coupled cluster method) code for lattice spin systems at T=0 by Damian J. J. Farnell (DF).
- Historically, this code is based on "foundations" laid by Ray Bishop and John Parkinson (amongst others), and Chen Zeng's work in the 90's on the high-order code.
- This code has been exploited and pushed forward by Damian Farnell and Sven Krüger primarily.
- Joerg Schulenburg (JS) improved this code greatly and he has set up this webpage for distribution of the most recent code.
