METHOD AND SYSTEM FOR TRACKING POSITIONS OF HUMAN EXTREMITIES
First Claim
1. A method for tracking positions of human extremities, comprising:
- retrieving a left image of a first extremity portion using a first picturing device;
obtaining an outline candidate position of the first extremity portion according to feature information of the left image;
retrieving a right image of the first extremity portion using a second picturing device;
obtaining a depth candidate position of the first extremity portion according to depth information of the right image;
calculating geometry relations between the outline candidate position and the depth candidate position and a second extremity portion of a second extremity position; and
determining whether a current extremity position of the first extremity portion is required to be updated.

Abstract
A method for tracking positions of human extremities is disclosed. A left image of a first extremity portion is retrieved using a first picturing device and an outline candidate position of the first extremity portion is obtained according to feature information of the left image. A right image of the first extremity portion is retrieved using a second picturing device and a depth candidate position of the first extremity portion is obtained according to depth information of the right image. Geometry relations between the outline candidate position and the depth candidate position and a second extremity portion of a second extremity position are calculated to determine whether a current extremity position of the first extremity portion is required to be updated.
