- CRA (Conditional Replenishment Algorithm) has been proposed to improve the visual quality of asymmetrical 3DTV where the resolutions of two views are not matched. CRA adopts variable-sized PU (Processing Unit) and quad-tree is employed to represent its hierarchical structure. In this paper, we determine the largest and smallest sizes of PU which reduce the complexity while keeping the quality degradation as small as possible. In case of HD resolution images, the processing time of CRA can be reduced to 60 % but the decrease of BD-PSNR is only 0.034 dB by limiting the size of PU from 4x4 to 128x128.
