1. A method for filling holes in a 3D wrapped image comprising: reducing the resolution of the 3D wrapped image until the number of holes, the size of the holes, or both contained in a reduced-resolution 3D wrapped image are below a predetermined threshold; expanding the reduced-resolution 3D wrapped image to produce an expanded 3D wrapped image; and using data from the expanded 3D wrapped image to fill holes in the 3D wrapped image.
