  • 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 ...
  • Berzhanskaya, Julia; Grossberg, Stephen; Mingolla, Ennio (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 2004-11)
    How do visual form and motion processes cooperate to compute object motion when each process separately is insufficient? A 3D FORMOTION model specifies how 3D boundary representations, which separate figures from backgrounds ...
  • Berzhanskaya, J.; Grossberg, S.; Mingolla, E. (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 2007-01)
    How do visual form and motion processes cooperate to compute object motion when each process separately is insufficient? Consider, for example, a deer moving behind a bush. Here the partially occluded fragments of motion ...
  • 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 ...
  • Kelly, Frank; Grossberg, Stephen (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1998-07)
    This article develops the FACADE theory of three-dimensional (3-D) vision to simulate data concerning how two-dimensional (2-D) pictures give rise to 3-D percepts of occluded and occluding surfaces. The theory suggests how ...
