    Abstract: PROBLEM TO BE SOLVED: To provide a method for tracking eye positions by which the eye positions can be tracked from a general facial image with high robustness and without unduly constraining a user. SOLUTION: The method for tracking the eye positions includes a step 242 for acquiring an image, a step 244 for predicting a middle forehead position of the facial image in the image, a step 246 for searching a point conforming to an image pattern of a middle forehead best in the vicinity of the predicted middle forehead position, a step 248 for predicting positions of both eyes in the image based on a position of the searched point and relative positions of both eyes and for searching a point to be the center of each of two areas satisfying conditions predetermined centering around the predicted areas and a step 254 for updating the middle forehead position, the relative positions of both eyes and the image pattern of the middle forehead.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for extracting eyes by which eye positions can be detected from a general face image without unduly constraining a user. SOLUTION: This method includes: a step 122 for calculating a differential image between two images to be outputted by a camera; a step 132 for cancelling a differential area due to transfer of a subject between the two images in the differential image and for extracting the remaining differential area based on the differential image and the two images; a step for selecting two candidate points for eyes from the extracted remaining differential area according to predetermined conditions; and a step for determining whether or not the two selected candidate points for the eyes satisfy the predetermined conditions and for extracting the two candidate points for the eyes as the eye positions when the predetermined conditions are satisfied.

    Abstract: PROBLEM TO BE SOLVED: To provide an object recognition device recognizing an object on the basis of a characteristic of appearance of the object itself and not by extracting the target object as a moving area or a particular color area. SOLUTION: A discrimination axis is determined by extracting geometrical structures of a background image and a person image picked up by a camera as a difference of picture element distributions and constructing a statistical model of appearance of the person image. The model and an inputted image are compared and a score is calculated on the basis of the discrimination axis of the model and a distance value vector of the inputted image. A recognition process is efficiently carried out by a small number of models by judging that a person has been detected when the score exceeds a threshold. COPYRIGHT: (C)2003,JPO
