Study on Defection Segmentation for Steel Surface Image Based on Image Edge Detection and Fisher Discriminant

A hybrid image segmentation method based on edge detection and Fisher discriminant is presented to detect defection, because signal-to-noise ratio of steel surface image is very low, and defection targets are small and their shape is irregular. Firstly, gradient operator detects the edge of defectio...
