Abstract: An image processing method includes determining a vertical baseline and a horizontal baseline corresponding to a boundary of an eye of a user in an input image of the eye of the user, and aligning the input image based on the vertical baseline and the horizontal baseline.

Abstract: An apparatus and method for estimating a pose of an object are provided. The apparatus includes an object input unit configured to input an object in an object tracking unit and an object identifying unit, an object tracking unit configured to obtain a tracked pose probability density of the object based on a tracking scheme, an object identifying unit configured to obtain an identified pose probability density of the object based on a training model, and a combination unit configured to obtain an estimated pose probability density of the object using a combination of the tracked pose probability density and the identified pose probability density and to estimate a pose of the object based on the estimated pose probability density of the object. Through the combination, a cumulative error occurring in the object tracking may be corrected, resulting in more accurate object estimation.

Abstract: An apparatus and method for tracking a gaze based on a camera array are provided. The apparatus may include a camera array including a plurality of cameras, and a plurality of light sources for the plurality of cameras, a light source controller to control the plurality of light sources so that the plurality of cameras capture a bright pupil image and a dark pupil image of a user, a detector to detect a position of a pupil center of the user, and a position of a glint caused by reflection of the plurality of light sources from the captured bright pupil image and the captured dark pupil image, and an estimator to estimate an interest position of eyes of the user by tracking a gaze direction of the eyes, based on the detected position of the pupil center and the detected position of the glint.
