Abstract
Due to the limited display capacity of multiview/ automultiscopic 3D displays (and other 3D display methods which recreate lightfields), regions and objects and greater depths from the zero disparity plane appear aliased. One solution to this, namely prefiltering renders the scene visually very blurry. An alternative approach is proposed in this paper, wherein regions are large depths are identified in each view. The 3D scene points corresponding to these regions is rendered as 2D only. The rest of scene still retains parallax (hence the depth perception). The advantages are that both aliasing and blur are removed, and the resolution of such regions is greatly improved. A combination of the 2D and 3D visual cues still make the scene look realistic, and the relative depth information between objects in the scene is still preserved. Our method can prove to be particularly useful for the 3D video conference application, where the people in the conference will be shown as 3D objects, but the background will be displayed as a 2D object with high spatial resolution.
