Contour Service
Description
Service for detecting and scoring wire/line contours from Vision results.
Acceptance Criteria
ContourServiceclass with methods:func findBestWireContour(at point: CGPoint, from contours: [VNContour]) -> VNContour?func scoreContour(_ contour: VNContour, relativeTo point: CGPoint) -> Floatfunc contourToMask(_ contour: VNContour, width: Int, imageSize: CGSize) -> CGImage
- Contour scoring considers:
- Proximity to tap point (closer = higher score)
- Aspect ratio (thin and elongated = higher score)
- Straightness / low curvature (straighter = higher score)
- Length (longer = higher score)
- Configurable mask width: default 6px, range 2-20px
- Returns
nilwhen no wire-like contour found near tap - Unit tests for contour scoring logic
Technical Notes
- VNContour provides normalized path points
- Calculate curvature by analyzing angle changes along path
- Aspect ratio = length / average width
- Weight scoring factors: proximity (0.3), aspect (0.3), straightness (0.2), length (0.2)
Edge Cases
- No contours detected: return nil
- All contours score below threshold: return nil
- Curved wires: allow moderate curvature, don't require perfectly straight
- Contour very close to tap but not wire-like: score should be low
