摘要：
An eye tracking method for determining a position of an eye or a part of an eye in an image of an image sequence by performing a comparison between said image and a reference image, said process including: aligning a set of images; computing an enhanced reference image based on a combination of said set of aligned images; and determining said position in said image of said image sequence by comparing said image of said image sequence and said enhanced reference image to yield a motion estimation between said reference image and said image of said sequence.
