An iterative scheme is presented which requires no prerequisite shape information. This scheme forms the basis for a parallel algorithm implemented on a CM-5. Performance of the CM-5 implementation is compared with that of a sequential implementation running on a Sun Sparc 2. Also considered are the complexity and scalability of the parallel algorithm as a function of image size and number of processors, respectively.en©1995 IEEEConference paper003003542110.1109/CAMP.1995.5210402-s2.0-0029483383214158Brooks, M.J.
