Beijing, China ABSTRACT erated depth data compression. However, as a low-cost structured light camera, the quality of the Kinect depth is The Kinect-like depth compression becomes increasingly limited by its generation principle and hardware constraints important due to the growing requirement on Kinect depth and suffers from spatial artifact and temporal inconsistency. data transmission and storage. Considering the temporal Therefore, the Kinect-like depth is more difficult to be com- inconsistency of Kinect depth introduced by the random pressed in comparison
