1. A method for classifying an anomaly of an object, the method comprising:

  • preparing a primitive-based representation of an object having an anomaly;

    comparing the primitive-based representation of the object to a primitive-based reference image to detect and locate the anomaly;

    selecting a descriptor for the anomaly, the descriptor associated with a plurality of descriptor values;

    determining a first descriptor value of the anomaly using the primitive-based representation;

    comparing the first descriptor value with a second descriptor value associated with a defect class;

    determining a match between the first descriptor value and the second descriptor value; and

    classifying the anomaly as a defect according to the defect class.
