Abstract
The authors propose a method to use slenderness ratio of hand area as well as the contour information of a large number of hand shapes in advance in a database, for estimation of the human hand posture with wrist rotation by a single camera. The experimental results showed that the standard deviation of estimation error in all finger joints and speed are 13.22degrees and 9〜13fps respectively, and 13.22degrees and 1.3fps respectively without the ratio of hand area, suggesting that our method is effective.
