Application of volume bounding box decomposition for surgeon's hand gestures recognition

Possibility to apply volume bounding box decomposition to surgeon's hand movements analysis and gesture recognition during laparoscope surgery is explored in this paper. Volume bounding box decomposition allows to approximate non-convex sets by a number of bounding boxes which leads fast and easy way to verify if given point belong to certain set or not. This unique feature is applied to analyze trajectories of surgeon's wrist and recognize different hand gestures.
