Gravity optimised particle filter for hand tracking

作者：

Highlights：

• Introduces Gravity Optimised Particle Filter (GOPF) to improve particle propagation.

• GOPF introduces gravitational force in addition to weighted particles.

• GOPF attracts particles towards peak of likelihood distribution to improve sampling.

• Introduces a fast detection and labelling of hand features using convexity defects.

• GOPF is incorporated in hand features tracking with a validation gate mechanism.
