Gaze correction for videoconferencing

One pressing problem of using webcams is the off-alignment of the camera with respect to a user’s gaze. This Final Year Project (FYP) will attempt to synthesize a gaze corrected (cyclopean) view using two stereo and synchronized webcams. The two webcams will be used to capture two separate live v...
