| Abstract(in English) | We have developed a real-time system which tracks the hands of a person doing sign language or hand gestures. The system enables us to track hands without markers or colored gloves even if the hands overlap the face. First, the system extracts the hand and face regions from the image sequence using an improved histogram backprojection. Next, the system computes blobs from both the extracted image and the time differential image between the continuous extracted images. Then, the system estimates these blobs and tracks the location of each hand using a Kalman Filter. The system has been tested for hand tracking using both the primitive motions by one hand and actual sign-language motion by native signers. The experimental results indicate that the system is able to track hands while the hand is overlapping the face. |
