this option is set as relatively low value, the background learning will be car-
ried out in a short time interval and vice versa.
Shadow Removal
> Activate: Check to activate the shadow removal function. If this option is set,
the region classified as shadow will be filtered among the final detection
results and vice versa.

detected objects with little movement progressively will be recognized as the
environment after certain amount of time (blind update). If this parameter is
not set, detected objects will never be recognized as the environment (selec-
tive update).

value, objects with little movement will be recognized as the background fast

relatively low value, the system will dully detect the movement, the veiling of
