Point distribution models are flexible shape models in which a shape is represented by a set of labelled points on the boundary. This paper uses techniques drawn from the Finite Element Method to include grey level information in such models. As both Point Distribution Models and the Finite Element Method represent objects using a set of labelled points, the techniques are very compatible. Results are presented which show that relatively complex objects, animal bodies, can be represented by a small number of elements. The method will eventually be used to improve the chances of successfully fitting Point Distribution Models to image data.
