A Contrast Adjustment Thresholding Method for Surface Defect Detection Based on Mesoscopy

Titanium-coated surfaces are prone to tiny defects such as very small cracks, which are not easily observable by the naked eye or optical microscopy. In this study, two new thresholding methods, namely contrast-adjusted Otsu's method and contrast-adjusted median-based Otsu's method, are pr...
