• Murase and
Nayar (1994, 1995) extended this idea to 3D
objects.
• The training set had multiple views of each object, on a
dark background.
• The views included multiple (discrete) rotations of the object on
a turntable and also multiple (discrete) illuminations.
• The system could be used first to identify the object and then
to
determine its (approximate) pose and illumination.
