1. A method comprising: computing a stereo disparity surface between a first image and a second image of a stereo image pair; computing an integer position on a virtual image plane from a projection between the virtual image plane and a center of projection through a projected point on the stereo disparity surface to the virtual image plane; and setting a pixel value of the integer position on the virtual image plane based on the projected point on the stereo disparity surface, wherein the setting operation comprises: setting the pixel value of the integer position on the virtual image plane to a pixel value from one or more integer positions of the first image that corresponds with the projected point on the stereo disparity surface, if one or more integer positions of the second image that corresponds with the projected point on the stereo disparity surface are occluded, wherein computing the stereo disparity surface, computing the integer position and setting the pixel value are controlled by a processor operating with a memory.
