Abstract: Images of the face of a subject are captured by an imaging system comprising at least three directional energy sources (e.g. a light sources), and an imaging assembly which captures the images from spatially separated viewpoints. Each eye portion of the face is modelled using specular reflections (“glints”) in at least some of the images to fit the parameters of a three-dimensional parameterized model of the eye surface. Additionally, using at least some the images, a photometric modelling process generates a second model of a skin and/or hair portion of the face. A face model is produced by combining the second model and the eye models. The resulting face model may be used to generate images of the face in relation to an object intended to be used in proximity to the face, such as an item of eyewear. The face model may also be used to design and produce the object.

Abstract: A method is proposed for identifying (“segmenting”) at least one portion of the skin of an animal which is a region of interest (e.g. a portion which is subject to an abnormality such as a tumor). The method uses at least a temperature dataset obtained by measuring the temperature of each of a plurality of points of a region of the skin. An initial segmentation may be performed using the temperature data based on a statistical model, in which each point is segmented based on its temperature and optionally that of its neighbors. The initial segmentation based on the temperature data may be improved using a three-dimensional model of the profile of the skin, and the enhanced segmentation may be used to improve the three-dimensional model.
