One-shot Radar-based Gesture Recognizer for Fast Prototyping

Millimeter-Wave radar is a promising sensor for contactless, privacy concerned user scenarios, e.g. interacting computers with gestures. But training a robust gesture recognizer requires a large dataset, which hinders fast prototyping. Here we propose One-Shot Gesture Recognizer, namely to use only one trajectory sample as template to recognize gesture. Due to high ambiguity of gesture itself, we extended protractor3d, giving a closed-form solution regardless of position, scale and direction.
