Date: June 24, 2015. Source: European Craniofacial Congress 2015, Gothenburg, Sweden. Summary: Being able to compare images is one of the core technologies of medical image analysis. In order to quantify change, e.g. due to growth or surgery, it is necessary to compare two or more images. And as part of population studies it is…

3D digital surface imaging for quantification of facial development and asymmetry in juvenile idiopathic arthritis. NV Hermann, TA Darvann, P Larsen, S Kreiborg.

Date: June 2015. Source: Seminars in Orthodontics, Volume 21, Issue 2, Pages 121–124. Abstract: 3D digital surface imaging (digital stereophotogrammetry or “3D photography”) is becoming an increasingly popular tool for quantification of the face, in clinical contexts as well as for research. The modality is easy to apply and is free from motion artifacts and…

Thesis: Three-dimensional age-related changes of the adult face: African American female population. TC Sutherland.

Date: June 2015 Source: 2015 12th Conference on Computer and Robot Vision (CRV) Proceedings (p 230 – 236), Halifax, Canada. Abstract: In tele-presence systems, direct face-to-face contact, is essential for emotional communication as it carries non-verbal clues. In commercial products, face-to-face contact is approximated by using either a large semi-transparent mirror to project an image…
