Claim 4:
5. A method comprising:
determining, based on facial detection, for a first image and a second image, a first detected landmark position of a landmark in the first image and a second detected landmark position of the landmark in the second image;
determining a first optical flow landmark position of the landmark in the first image and a second optical flow landmark position of the landmark in the second image, wherein the first optical flow landmark position is based on optical flow of the landmark from the first detected landmark position to a second optical flow position in the second image and optical flow from the second optical flow position in the second image back to the first optical flow landmark position in the first image; and
determining a weighted position of the landmark in the second image by weighting a detected landmark position of the landmark in the second image and an optical flow landmark position of the landmark in the second image, wherein the weighted position is based on a first distance between the first detected landmark position and the first optical flow landmark position and a second distance between the first detected landmark position and the second optical flow landmark position.
