     11Description
     12===========
     13
     14Proprietary format used by Intel RealSense Depth cameras containing depth
     15confidence information in range 0-15 with 0 indicating that the sensor was
     16unable to resolve any signal and 15 indicating maximum level of confidence for
     17the specific sensor (actual error margins might change from sensor to sensor).
     18
     19Every two consecutive pixels are packed into a single byte.
     20Bits 0-3 of byte n refer to confidence value of depth pixel 2*n,
     21bits 4-7 to confidence value of depth pixel 2*n+1.
