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.
