Abstract
A method and apparatus for obtaining well defined surface descriptions from a three-dimensional image. The invention employs an imaging and graphic system to receive as input an image and initial surface of points. The surface of points are modified in the memory of the graphic system to conform to the surface they represent by continually shrinking the points until they conform precisely to the surface to be matched. The resulting set of vectors are displayed by the graphic system. The integrated graphics and imaging system provides remarkable improvements in representing the surface.
