Detailed Description

Codec for lossless compression of 11 bit depth images (like Kinect depth images) that can be used together with a BinarySerializer.

Depth images are compressed using a Variable Bit Width Encoding (ZBWE). The codec computes the depth value differences between consecutive pixels. Smaller differences occur more often in depth images and are stored using few bits only. Larger differences are stored with more bits, but their occurrence is rare.
