The present invention relates to a method for locating the eyes in an image of a person, for example useful in eye-tracking. The method comprises selecting a region of interest in the image, preferably including the face of the person, using information from said selection in the steps of: selecting a plurality of candidate areas ("blobs) in this region of interest, matching said candidate areas of an edge map of the image with at least one mask based on a geometric approximation of the iris, selecting the best matching pair of candidate areas, and evaluating the relative geometry of said selected candidate areas to determine if the pair of candidate areas is acceptable. The key principle of the invention is to use information from the face detection to improve the algorithm for finding the eyes. |
