Optimal pixel aspect ratio for stereoscopic 3D displays under practical viewing conditions

In multiview 3DTVs the original 3D-scene is reconstructed based on the corresponding pixels of adjacent 2D views. For conventional 2D display the highest image quality is usually achieved by uniform distribution of pixels. However, recent studies on the 3D reconstruction process show that for a given total resolution, a non-uniform horizontally-finer resolution yields better visual experience on 3D displays. Unfortunately, none of these studies explicitly model practical viewing conditions, such as the role of the 3D display as a medium and behavior of the human eyes. In this paper the previous models are extended by incorporating these factors into the optimization process. Based on this extended formulation the optimal ratios are calculated for a few typical viewing configurations. Some supporting subjective studies are presented as well.
