Mathematical morphology
Morphology processes shapes using a structuring element (SE): erosion shrinks foreground, dilation grows it; openings remove speckles, closings fill gaps.
Duality
Erosion on foreground relates to dilation on background—design SE size/shape for the defect scale you target.
Operators
Erosion
Local minimum over SE support—removes thin protrusions, separates touching objects if SE fits.
Dilation
Local maximum—bridges small gaps, thickens strokes.
Opening
Erosion then dilation—suppresses bright noise smaller than SE.
Closing
Dilation then erosion—fills dark holes smaller than SE.
