윤곽선 감지

모든 이미지에서 개체 주위의 윤곽을 식별하고 그립니다. 형상 분석, 객체 계산 및 경계 시각화에 유용합니다.

분할 및 컴퓨터 비전 디버깅을 위해 이미지 윤곽선을 감지하고 닫힌 모양, 영역 및 객체 경계의 윤곽을 잡습니다.

Frequently Asked Questions

What is contour detection?

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.

What is the difference between external and all contours?

External mode detects only outermost contours (no nested boundaries). All mode returns every contour including holes. Tree mode preserves the parent-child hierarchy.
