1. A method of detecting one or more artifacts in a virtual image synthesized from stereo images, the method comprising:

  • generating a disparity map from the stereo images;

    generating a projected image for each of the stereo images by projecting each stereo image into a target viewpoint based on the disparity map;

    computing color-distances between corresponding pixels in the projected images to produce a difference map; and

    designating one or more locations in the difference map associated with a computed color-distance exceeding a threshold as the one or more artifacts.
