| Abstract: | This paper presents an integrated theory of edge detection, curvature measurement and motion detection during the earliest stages of visual processing. No assumptions are necessary about the viewed objects or about surface properties and the viewing geometry. New methods are outlined for edge detection, curvature measurement and correspondence matching by successive refinement. |
