Background
Fig. 11: Background
The background settings allow modeling and updating the background by setting the entry time of an object
in the background
The output is an image in the YUV420 color space which represents the static part of the scene shot; it is
then used to determine the dynamic part of the current frame, that is the foreground mask.
Update latency (s): Time period in seconds after a change in the scene must definitely become part of the
background
Threshold (YUV): A comparison is made between the current frame and the background image of the
previous instant: if the pixel of the frame is "close" to the corresponding pixel of the background, then it is
not a foreground pixel; otherwise, that pixel will be white in the foreground mask. The comparison is made
separately on each of the three YUV channels
