Abstract
Human faces differ in shape and texture. This paper describes a representation of grey-level images of human faces based on an automated separation of two- dimensional shape and texture. The separation was done using the point correspondence between the different images, which was established through algorithms known from optical flow computation. A linear description of the separated texture and shape spaces allows a smooth modeling of human faces. Pictures of faces along the principal axes of a small data set of 50 faces are shown. We also show face reconstructions based on this small example set.
