axiom-vision

Guides you through implementing computer vision: subject segmentation, hand/body pose detection, person detection, text recognition, barcode detection, document scanning, and combining Vision APIs to solve complex problems. Use when you need to: "How do I isolate a subject from the background?" "I need to detect hand gestures like pinch" "How can I get a bounding box around an object without including the hand holding it ?" "Should I use VisionKit or Vision framework for subject lifting?" "How do I segment multiple people separately?" "I need to detect body poses for a fitness app" "How do I preserve HDR when compositing subjects on new backgrounds?" "How do I recognize text in an image?" "I need to scan QR codes from camera" "How do I extract data from a receipt?" "Should I use DataScannerViewController or Vision directly?" "How do I scan documents and correct perspective?" "I need to extract table data from a document" Signs you're making this harder than it needs to be: Before implementing any Vision feature: NEVER run Vision on main thread : Processing video frames? Use VNSequenceRequestHandler (maintains inter-frame state for temporal smoothing). For single images, use VNImageRequestHandler . Creating a new VNImageRequestHandler per frame discards temporal context and causes jittery results. See axiom-vision-ref for full comparison and code examples. User's original...
