Abstract
A hierarchical stereo system is described that uses structural
descriptions up to the surface level. Surface descriptions are computed
from monocular images, by using a perceptual grouping technique.
Occlusion can be a major problem in stereo analysis and is often not
treated explicitly. An analysis is presented of occlusion effects in
stereo, and it is shown how structural descriptions can be used to deal
with them. Experimental results are given for scenes with curved objects
and significant occlusions
