handpose_estimation_mediapipe

Hand pose estimation from MediaPipe Handpose

This model estimates 21 hand keypoints per detected hand from palm detector. (The image below is referenced from MediaPipe Hands Keypoints)

This model is converted from TFlite to ONNX using following tools:

• TFLite model to ONNX: https://github.com/onnx/tensorflow-onnx
• simplified by onnx-simplifier

Note:

• The int8-quantized model may produce invalid results due to a significant drop of accuracy.
• Visit https://github.com/google/mediapipe/blob/master/docs/solutions/models.md#hands for models of larger scale.

Demo

Run the following commands to try the demo:

# detect on camera input
python demo.py
# detect on an image
python demo.py -i /path/to/image -v
