METHOD AND APPARATUS FOR IMAGE-BASED EYE TRACKING FOR RETINAL DIAGNOSTIC OR SURGERY DEVICE

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; anddetermining 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.

主权项

1. A method of enhancing the video display of an image of an eye or a portion of an eye, said method comprising:
aligning a sequence of images which are preceding an actual image of said video stream with respect to said actual image; combining the resulting aligned set of images into an enhanced image to be used as a basis for an enhanced actual image of said video stream.
