Contour detection finds continuous curves that form the boundaries of objects in an image. It is used in shape analysis, object counting, gesture recognition, and industrial inspection.
External mode detects only outermost contours (no nested boundaries). All mode returns every contour including holes. Tree mode preserves the parent-child hierarchy.
