-All scripts are updated and working with the new dict-based API! 🎉
-
---
-
-## 📝 Notes
-
- All scripts now use the factory functions (`create_detector`, `create_recognizer`)
- Scripts work with the new dict-based detection API
- Model download bug is fixed (enum vs string issue)
- CoreML acceleration is automatically detected on Apple Silicon
- All scripts include proper error handling
-
