- Minimum and maximum value among all pixels
Combined with (adaptive) background subtraction, such values are useful to detect sudden changes or out-of-the-ordinary frames in a video stream.
Input[edit | edit source]

Output[edit | edit source]
The statistical values are written to the NMEA stream.
Parameters[edit | edit source]
