ABSTRACT:
A three-dimensional object X is recognized by a method which includes the steps of: a) storing in a memory, a set of two-dimensional enrollment images X.sub.1 -X.sub.n of the object X as viewed from n different directions; b) acquiring a two-dimensional access image of an unidentified object as viewed from a new direction which lies between the n different directions; c) generating, from the stored set of images, a rotated two-dimensional image of the object X as viewed from a direction which is closer to the new direction than any of the n different directions; and, d) identifying the unidentified object as the object X only if a correlation between the image of the unidentified object and the rotated image exceeds a predetermined threshold. By generating the rotated image, misalignments with the access image of the unidentified object are reduced; and thus the predetermined threshold can be raised to reduce recognition errors.
