||A method for summarising and clustering forms is described which should be observer-invariant. The method is illustrated by using points selected along a horizontal cross-section of the head. The points are first transformed into values called curvatures which are subsequently transformed into a series of Fourier coefficients used for arriving at shape clusters or groupings. The shape differences and similarities within and between clusters are examined graphically and discussed. Methods of extending the technique to the three-dimensional case are also discussed.
