Recognition of Head Gestures Using a Sequence of Range Images.
Kazunori Umeda, Norihito Suzuki · Journal of the Robotics Society of Japan · 1999
Gesture recognition using images is recently studied as a technology of human friendly man-machine interface. In this paper, recognition of 3D gesture by using range images is discussed. Two methods for recognizing head gestures from a sequence of range images are proposed. One uses differential range images for identifying ‘Yes’ motion, and the other detects and tracks nose position for identifying ‘Yes’ and ‘No’ motion. Experiments to recognize real person's gestures using a range sensor system are performed to show the effectiveness of the presented methods.
