Code for Hand Key point Detector

Model architecture

Model consists of two parts:

• Detector: predicts bounding box for single hand
• Key point model: predicts coordinates for fingers.

Code

• detector.py: code for detector model
• kp_model.py: code for key point model
• cursor.py: Cursor class uses both aforementioned models to track hand
• main.py: runs Cursor activity on video stream from camera using opencv and displays some statistics

FPS

On MacBook pro 2017 I got following statistics:

• Detector model: 5-6 fps
• KeyPoint model: ~10 fps
