Statistical considerations in climate reconstruction from proxy data To understand recent climate trends and possible future change it is necessary to examine the nature of past climatic variability. It is well-established practice to reconstruct climate parameters from proxy variables using a transfer function derived from training data. Historical proxy measurements can then be used to extend records beyond the limited period of instrumental measurements. Computerised 3D facial reconstruction. The purpose of forensic facial reconstruction is to produce an image from a skull which offers a sufficient likeness of the living individual that it will facilitate identification of skeletal remains.
Traditional methods use modelling clay to build up the depth of tissue on the skull.
Standard tissue depths are used for 'landmark' sites on the skull, but the shape of the eyes, nose and mouth are largely guesswork. More recently, computerised methods for 3D facial reconstruction have been developed. These methods employ computer programs to transform laser-scanned 3D skull images into faces. This talk will briefly describe the traditional method, and outline the novel approach being adopted in the computerised 3D forensic facial reconstruction project at the University of Sheffield.
