ABSTRACT:
Methods and apparatus for automatically tracking the position of a moving object in real time, particularly the face of a person who is being fed by a robotic system, is disclosed. The object can be tracked by comparing a prestored object model image with the current image of the object using the square-distance criteria. The search area can be limited to a region in which the face is most likely to be found and the prestored object model image can be limited to robust points. The method can include motion prediction, including both continuous motion and sudden motion, such as the motion cause by a person sneezing. Alternatively, a computationally efficient approach employing a one-dimensional algorithm can be used.
