Abstract
The problem of determining the identity and pose of occluded
objects from noisy data is examined. Previous work has shown that local
measurements of the position and surface orientation of small patches of
an object's surface may be used in a constrained search process to solve
this problem, for the case of rigid polygonal objects using 2-D sensory
data, or rigid polyhedral objects using 3-D data. The recognition system
is extended to recognize and locate curved objects. The extension is
done in two dimensions, and applies to the recognition of 2-D objects
from 2-D data, or to the recognition of the 3-D objects in stable
positions from 2-D data
