Abstract
Apparatus and method for automatically inspecting objects and identifying or recognizing known and unknown portions thereof, including defects and the like, involving storing digital signal information representing an image of the desired predetermined object shapes to be learned by an image inspecting system and recognized during scanning of objects to be inspected, and modifying the stored digital signal information to create a fictitious image of the object shapes to be learned that incorporates acceptable size or dimension variations and the like in such objects such that during the inspecting of future objects, these acceptable variations will be ignored as defects or unknown elements.
