    • Relaxing the Brightness Constancy Assumption in Computing Optical Flow 

      Gennert, Michael A.; Negahdaripour, Shahriar (1987-06-01)
      Optical flow is the apparent (or perceived) motion of image brightness patterns arising from relative motion of objects and observer. Estimation of the optical flow requires the application of two kinds of constraint: ...

    • Synapses That Compute Motion 

      Poggio, Tomaso A; Koch, C. (1987-06-01)
      Biophysics of computation is a new field that attempts to characterize the role in information processing of the several biophysical mechanisms in neurons, synapses, and membranes that have been uncovered in recent ...

    • Visual Integration and Detection of Discontinuities: The Key Role of Intensity Edges 

      Gamble, Ed; Poggio, Tomaso (1987-10-01)
      Integration of several vision modules is likely to be one of the keys to the power and robustness of the human visual system. The problem of integrating early vision cues is also emerging as a central problem in current ...
