Abstract:
A method for associating a descriptive label with an anomaly on a manufactured object, the method comprising:placing the manufactured device on a moveable stage;capturing and preparing a digital-pixel-based representation of the image;symbolically decomposing the digital-pixel-based representation of the image to create a primitive-based representation of the image;comparing the primitive-based representation of the image to a primitive-based reference image to detect and locate the anomaly;isolating primitives associated with the anomaly;comparing the isolated primitives with primitives in a knowledgebase to locate a set of primitives in the knowledgebase most like the isolated primitives associated with the anomaly; andassigning a label associated with the set of primitives in the knowledgebase that was most similar to the isolated primitives, wherein highly-determinative primitives in the knowledgebase are weighted more heavily than others to assist in arriving at a more accurate label.
