Clone this repository:\n```bash\ngit clone https://github.com/yourusername/signlanguage.git\ncd signlanguage\n```\n\n2. Install required packages:\n```bash\npip3 install opencv-python mediapipe numpy picamera \"picamera[array]\" psutil\n```\n\n## Usage\n\n1. Connect your Raspberry Pi camera module and enable it in raspi-config\n\n2. Run the detector:\n```bash\npython3 sign_language_detector.py\n```\n\n3. Controls:\n   - Press 'd' to toggle debug mode (shows finger states and confidence levels)\n   - Press 'q' to quit the application\n\n## Supported Letters\n\nThe system currently detects the following ASL letters:\n- A: Closed fist with thumb to the side\n- B: All fingers extended upward\n- C: Curved hand shape\n- D: Index finger up, others closed\n- E: All fingers closed\n- F: Three fingers extended\n- G: Index and thumb pointing\n- H: Two fingers pointing sideways\n- I: Pinky extended\n- K: Index and middle finger in 'V' with thumb between\n- L: L-shape with thumb and index finger\n- M: Closed fingers over thumb\n- R: Crossed fingers\n- S: Closed fist with thumb over fingers\n- U: Two fingers extended together\n- V: V-shape with index and middle finger\n- W: Three fingers extended in W shape\n- Y: Thumb and pinky extended\n\n## Debug Mode\n\nDebug mode provides visual feedback including:\n- Hand landmark points\n- Finger state indicators (CLOSED, EXTENDED, HALF BENT, PARTIALLY BENT)\n- Confidence scores for each detected letter\n- Hand orientation (Vertical/Horizontal)\n\n## Performance Notes\n\n- The system is optimized for Raspberry Pi performance with automatic process priority adjustment\n- Frame rate is set to 15 FPS for optimal balance between performance and accuracy\n- Garbage collection is performed periodically to manage memory usage\n\n## Known Limitations\n\n- Requires good lighting conditions\n- Hand should be clearly visible in frame\n- Best results when hand is oriented vertically\n- Detection accuracy may vary based on hand position and lighting\n\n## Contributing\n\nFeel free to submit issues, fork the repository, and create pull requests for any improvements ","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fshauryasucksatgames%2Fsignlanguage","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fshauryasucksatgames%2Fsignlanguage","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fshauryasucksatgames%2Fsignlanguage/lists"}
