Claim 16:
17. The system of claim 10, wherein the defect type comprises a pit defect and a protrusion defect, and the circuitry is further configured to:
when the defect type of the defect region is a pit defect, if both the segmented 2D defect mask and the segmented 3D defect mask comprise the detect region, or the depth of the defect region is greater than a predefined threshold for the pit defect, output a defect class as the defect detection result; or
when the defect type of the defect region is a protrusion defect, if both the segmented 2D defect mask and the segmented 3D defect mask comprise the defect region, and the size and the depth of the defect region are greater than predefined thresholds for the protrusion detect, output a defect class as a defect detection result.
