iOS Computer Vision Router

You MUST use this skill for ANY computer vision work using the Vision framework.

When to Use

Use this router when:

  • Analyzing images or video
  • Detecting objects, faces, or people
  • Tracking hand or body pose
  • Segmenting people or subjects
  • Lifting subjects from backgrounds
  • Recognizing text in images (OCR)
  • Detecting barcodes or QR codes
  • Scanning documents
  • Using VisionKit or DataScannerViewController
  • Integrating with Visual Intelligence (iOS 26+ system camera feature)

Routing Logic

Vision Work

Implementation patterns/skill axiom-vision

  • Subject segmentation (VisionKit)
  • Hand pose detection (21 landmarks)
  • Body pose detection (2D/3D)
  • Person segmentation
  • Face detection
  • Isolating objects while excluding hands
  • Text recognition (VNRecognizeTextRequest)
  • Barcode/QR detection (VNDetectBarcodesRequest)
  • Document scanning (VNDocumentCameraViewController)
  • Live scanning (DataScannerViewController)
  • Structured document extraction (RecognizeDocumentsRequest, iOS 26+)

API reference/skill axiom-vision-ref

  • Complete Vision framework API
  • VNDetectHumanHandPoseRequest
  • VNDetectHumanBodyPoseRequest
  • VNGenerateForegroundInstanceMaskRequest
  • VNRecognizeTextRequest (fast/accurate modes)
  • VNDetectBarcodesRequest (symbologies)
  • DataScannerViewController delegates
  • RecognizeDocumentsRequest (iOS 26+)
  • Coordinate conversion patterns

Visual Intelligence integration/skill axiom-vision-ref (see Visual Intelligence Integration section)

  • Making app content discoverable to Visual Intelligence camera
  • IntentValueQuery and SemanticContentDescriptor
  • Deep linking from Visual Intelligence results

Diagnostics/skill axiom-vision-diag

  • Subject not detected
  • Hand pose missing landmarks
  • Low confidence observations
  • Performance issues
  • Coordinate conversion bugs
  • Text not recognized or wrong characters
  • Barcodes not detected
  • DataScanner showing blank or no items
  • Document edges not detected

Decision Tree

  1. Implementing (pose, segmentation, OCR, barcodes, documents, live scanning)? → vision
  2. Visual Intelligence system integration (camera feature, iOS 26+)? → vision-ref (Visual Intelligence section)
  3. Need API reference / code examples? → vision-ref
  4. Debugging issues (detection failures, confidence, coordinates)? → vision-diag

Anti-Rationalization

Thought Reality
"Vision framework is just a request/handler pattern" Vision has coordinate conversion, confidence thresholds, and performance gotchas. vision covers them.
"I'll handle text recognition without the skill" VNRecognizeTextRequest has fast/accurate modes and language-specific settings. vision has the patterns.
"Subject segmentation is straightforward" Instance masks have HDR compositing and hand-exclusion patterns. vision covers complex scenarios.
"Visual Intelligence is just the camera API" Visual Intelligence is a system-level feature requiring IntentValueQuery and SemanticContentDescriptor. vision-ref has the integration section.

Critical Patterns

vision:

  • Subject segmentation with VisionKit
  • Hand pose detection (21 landmarks)
  • Body pose detection (2D/3D, up to 4 people)
  • Isolating objects while excluding hands
  • CoreImage HDR compositing
  • Text recognition (fast vs accurate modes)
  • Barcode detection (symbology selection)
  • Document scanning with perspective correction
  • Live scanning with DataScannerViewController
  • Structured document extraction (iOS 26+)

vision-diag:

  • Subject detection failures
  • Landmark tracking issues
  • Performance optimization
  • Observation confidence thresholds
  • Text recognition failures (language, contrast)
  • Barcode detection issues (symbology, distance)
  • DataScanner troubleshooting
  • Document edge detection problems
