Transparency is the perception of
multiple surfaces at the same location and it can be induced by
luminance, motion or binocular cues. Motion and binocular transparency
are particularly interesting stimuli to use in the investigation of the
correspondence problem (i.e. knowing which features are matched between
images). We have measured the efficiency of human observers to perceive
two surfaces in transparency. We have also looked for the constraints
used by human observers to solve the correspondence problem.
