Abstract
Techniques are disclosed for generating stereoscopic images. The techniques include receiving a first image frame associated with a first eye, and receiving a first depth frame associated with the first eye. The techniques further include reprojecting the first image frame based on the first depth frame to create a second image frame associated with a second eye. The techniques further include identifying a first pixel in the second image frame that remains unwritten as a result of reprojecting the first image frame, and determining a value for the first pixel based on a corresponding pixel in a prior image frame associated with the second eye. One advantage of the disclosed techniques is that DIBR reprojected image frames have a more realistic appearance where gaps are filled using pixels from a prior image for the same eye.
