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