Abstract
Art identification becomes more and more sophisticated today, so the conventional testing or visual inspection is difficult to ensure accurate detection of small defects. This paper presents a computer-based defect detection method for artworks. It adopts small components removing method to remove image noise and any parts interfering measurements, and maximum variance method as threshold method of the detection system. Pixel and sub-pixel level edge detection methods are used to overcome the shortcomings of traditional methods to complete the defect detection. Experiments show that the scheme is feasible, and has high accuracy and shorter detection time.
