摘要：A method of filtering glints by processing an image of a user's cornea to obtaincoordinates of desired glints from a configuration of light sources, comprising processingan image, in a first image space, of a user's cornea to determine coordinates of respectivemultiple positions of glints; and iteratively: selecting from the coordinates a first and a

second set of coordinates; computing from the first set of coordinates a transformationthat transforms the first set of coordinates into first coordinates of a predeterminedspatial configuration; and testing whether the transformation transforms also the secondset into positions that match second positions of the predetermined configuration. Thecoordinates of the desired glints are selected as those first and second sets which aretransformed into coordinates that match the first and second coordinates of thepredetermined configuration. The method is based on a geometrical homography and isexpedient for robust gaze estimation in connection with e.g. eye tracking.
