Intuitively a boundary in an N-dimensional digital space is a
connected component of the (N-1)-dimensional surface of a connected
object. In this talk I explain these concepts and show that the boundaries
so specified have properties that are intuitively desirable. I describe some
efficient algorithms for tracking such boundaries and show that they can
be used for computer graphic displays of internal structures of the human
body based on the output of a medical imaging device.
