Abstract:
An apparatus and method for transmitting graphical representations is disclosed. The present invention has an image generator (112) that generates an image (114) of a head (106) with facial features, including an eye portion (202) that correlates to an eye (240) in the head (106). The apparatus also has a non-updating tracker (116) that searches for an eye target image of the eye (240) in the head (106). The eye portion (202) correlating to the eye (240) is positioned at the target image located by the non-updating tracker (116). The apparatus also has an updating tracker (118) that searches for an updated eye target image when the non-updating tracker (116) is unable to locate the eye target image. The updating tracker (118) also positions the eye portion (202) at the updated eye target image and updates the updated eye target image with the eye portion (202). The updating tracker further determines the location of the eye portion (202). The apparatus also has an image differentiator (120) coupled to the trackers for providing image differential signals (124), including eye differential signals representing positional difference from the location of the eye portion (202). The apparatus also has a display device (130) that receives the image differential signals (124), including the eye differential signals, and animates a model (136) with the received image differential signals (134).
