    • 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" ...

    • Conditions for Viewpoint Dependent Face Recognition 

      Schyns, Philippe G.; Bulthoff, Heinrich H. (1993-08-01)
      Poggio and Vetter (1992) showed that learning one view of a bilaterally symmetric object could be sufficient for its recognition, if this view allows the computation of a symmetric, "virtual," view. Faces are roughly ...
