CTRL Annotate 2 - SAM2 Polygon Export & Group Selection

The ultimate desktop annotation tool for YOLO and SAM2 segmentation models.

✨ What's New

🎯 SAM2 Polygon Export

  • Dual export formats - Choose YOLO (bounding boxes) or SAM2 (polygons)
  • Automatic polygon extraction - One-click generates precise segmentation masks
  • JSON export - Polygon coordinates with metadata for segmentation training

🔗 Group Selection Mode

  • Multi-point prompts - Shift+Click to select multiple parts of the same object
  • Combine regions - Click head, torso, legs → merged into one polygon
  • Live preview - See combined mask as you add points
  • Enter to confirm, Esc to cancel

🚀 Improved Performance

  • WebGPU acceleration - Automatic GPU detection with intelligent fallback
  • ~2 second embedding - Fast processing via HuggingFace Transformers.js 3.0
  • fp16 → fp32 → WASM - Tries fastest option, falls back gracefully
