We present a 3-D shape-based object recognition system for
simultaneous recognition of multiple objects in scenes
containing clutter and occlusion. Recognition is based on
matching surfaces by matching points using the spin-image
representation. The spin-image is a data level shape
descriptor that is used to match surfaces represented as
surface meshes. We present a compression scheme for spin images
that results in efficient multiple object recognition
which we verify with results showing the simultaneous
recognition of multiple objects from a library of 20 models.
Furthermore, we demonstrate the robust performance of
recognition in the presence of clutter and occlusion through
analysis of recognition trials on 100 scenes.
