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

Hand gesture classification demo (0-9)

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.
• handpose_estimation_mediapipe_2023feb_int8bq.onnx represents the block-quantized version in int8 precision and is generated using block_quantize.py with block_size=64.

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
