Electrical Engineering Department of National Cheng Kung University Smart Media & Intelligent Living Excellence Lab. Post-Processing We apply occlusion treatment via left/right consistency checking to check the condition. Then we fill in the disparity for invalidated pixels. For an invalidated pixel, we search its closest valid pixel to the left and to the right. 8
