See the text for details.<BR>|| Bipoles through the ages. (Grossberg 1984; Grossberg, Mongolla 1985). (Field, Hayes, Hess 1993) "association field". (Heitger, von der Heydt 1993). (Williams, Jacobs 1997). cf. "relatability" geometric constraints on which countours get to group (Kellman & Shipley 1991). Also "tensor voting" (Ullman, Zucker, Mumford, Guy, Medioni, ...).
