1. Apparatus for generating 3D models of individuals from 2D images, said apparatus comprising: a data store operable to store a 3D model defining the relative 3D locations of a plurality of points on the surface of a generic individual; a feature identifier operable to process 2D images of individuals to identify a number of points in said images as 2D co-ordinate locations of a number of features of said individuals in said images; and a modelling unit operable to process said 2D images of individuals and said identified 2D co-ordinate locations of features to generate 3D models of said individuals, said modelling unit being operable to generate said 3D models by associating said identified 2D co-ordinate locations of features with data indicative of relative 3D locations for said features determined utilising the relative 3D locations of corresponding features defined by a 3D model stored in said data store.
