    • Geometric and Algebraic Aspects of 3D Affine and Projective Structures from Perspective 2D Views 

      Shashua, Amnon (1993-07-01)
      We investigate the differences --- conceptually and algorithmically --- between affine and projective frameworks for the tasks of visual recognition and reconstruction from perspective views. It is shown that an affine ...

    • 3D Object Recognition: Symmetry and Virtual Views 

      Vetter, Thomas; Poggio, Tomaso; B'ulthoff, Heinrich (1992-12-01)
      Many 3D objects in the world around us are strongly constrained. For instance, not only cultural artifacts but also many natural objects are bilaterally symmetric. Thoretical arguments suggest and psychophysical ...

    • Example Based Image Analysis and Synthesis 

      Beymer, David; Shashua, Amnon; Poggio, Tomaso (1993-11-01)
      Image analysis and graphics synthesis can be achieved with learning techniques using directly image examples without physically-based, 3D models. In our technique: -- the mapping from novel images to a vector of "pose" ...
