Low-Complexity, Near-Lossless Coding of Depth Maps from Kinect-Like Depth Cameras

Depth cameras are gaining interest rapidly in the

market as depth plus RGB is being used for a variety of applications

ranging from foreground/background segmentation, face

tracking, activity detection, and free viewpoint video rendering.

In this paper, we present a low-complexity, near-lossless codec for

coding depth maps. This coding requires no buffering of video

frames, is table-less, can encode or decode a frame in close to

5ms with little code optimization, and provides between 7:1 to

16:1 compression ratio for near-lossless coding of 16-bit depth

maps generated by the Kinect camera.
