Abstract:
Nearest-neighbor correlation-based similarity computation in the space
of outputs of complex-type receptive fields can support robust
recognition of 3D objects. Our experiments with four collections of
objects resulted in mean recognition rates between 84% (for
subordinate-level discrimination among 15 quadruped animal shapes) and
94% (for basic-level recognition of 20 everyday objects), over a
40deg X 40deg range of viewpoints, centered on a stored canonical view
and related to it by rotations in depth. This result has interesting
implications for the design of a front end to an artificial object
recognition system, and for the understanding of the faculty of object
recognition in primate vision.
