# Hand pose estimation from MediaPipe Handpose

This model estimates 21 hand keypoints per detected hand from [palm detector](../palm_detection_mediapipe). (The image below is referenced from [MediaPipe Hands Keypoints](https://github.com/tensorflow/tfjs-models/tree/master/hand-pose-detection#mediapipe-hands-keypoints-used-in-mediapipe-hands))

This model is converted from Tensorflow-JS to ONNX using following tools:
- tfjs to tf_saved_model:  https://github.com/patlevin/tfjs-to-tf/
- tf_saved_model to ONNX: https://github.com/onnx/tensorflow-onnx
- simplified by [onnx-simplifier](https://github.com/daquexian/onnx-simplifier)

## Demo

Run the following commands to try the demo:
```bash
# detect on camera input
python demo.py
# detect on an image
python demo.py -i /path/to/image
```
