Paper Abstract

Automated defect detection from optical images is an efficient non-destructive evaluation technique for surface and structure health inspection. Background subtraction is a widely-used technique for automated defect detection. In background subtraction, an image of the part with no defect, called background image, is generated and subtracted from the defective part image; the resulted large differences are then considered as defects. In this paper, a new background generation technique is proposed that allows for efficient defect detection at a low-computational load. In this technique, a defect-free region is generated by approximately locating defects and removing them from the original image. The resulted defect-free region is now used to generate the background. The procedure and performance of the algorithm is illustrated by an example.
