Simplified gaze-correction method using 3D mesh warping

Under the typical video communication configuration in which a camera is placed on top or at lateral side of a monitor, the face-to-face video communication has an inherent difficulty of poor eye contacts since the users stare at the monitor screen rather than directly seeing the camera lens. In this paper, me propose an image warping technique for gaze-correction which performs 3D warping of face object in the given image by a certain correction angle. The correction angle which is the angle between the direction of eye gaze and that to the camera is estimated in an unsupervised way by using eye tracking technique. Experimental result with real image data shows much enhanced naturalness which the face-to-face video communication has to offer.
