Extended Guided Filtering for Depth Map Upsampling
Kai‐Lung Hua, Kai-Han Lo, Yu-Chiang Frank Frank Wang · IEEE Multimedia · 2015
This extended guided filtering approach for depth map upsampling outperforms other state-of-the-art approaches by using a high-resolution color image as a guide and applying an onion-peeling filtering procedure that exploits local gradient information of depth images.
