  • Grossberg, Stephen (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1993-05)
    A neural network theory of :3-D vision, called FACADE Theory, is described. The theory proposes a solution of the classical figure-ground problem for biological vision. It does so by suggesting how boundary representations ...
  • Santini, Fabrizio; Rucci, Michele (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 2005-01)
    Many visual cues, both binocular and monocular, provide 3D information. When an agent moves with respect to a scene, an important cue is the different motion of objects located at various distances. While a motion parallax ...
  • Grossberg, Stephen; McLoughlin, Niall (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1995-07)
    Previous models of stereopsis have concentrated on the task of binocularly matching left and right eye primitives uniquely. A disparity smoothness constraint is often invoked to limit the number of possible matches. These ...

  • Grossberg, Stephen; Howe, Piers D.L. (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 2002-02)
    A laminar cortical model of stereopsis and later stages of three-dimensional surface perception is proposed and simulated. The model describes boundary and surface interactions between LGN, V1, V2, and V4, and details how ...
  • Howe, Piers D.L.; Watanabe, Takeo (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 2002-03)
    The same-sign hypothesis suggests that only those edges in the two retinal images whose luminance gradients have the same sign can be stereoscopically fused to generate a perception of depth. If true, one would expect that ...
  • Grunewald, Alexander; Grossberg, Stephen (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1996-10)
    This article develops a neural model of how sharp disparity tuning can arise through experience-dependent development of cortical complex cells. This learning process clarifies how complex cells can binocularly match left ...
  • Grossberg, Stephen (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1992-10)
    A neural network model of 3-D visual perception and figure-ground separation by visual cortex is introduced. The theory provides a unified explanation of how a 2-D image may generate a 3-D percept; how figures pop-out from ...
