Parameter
Description
Shadow removed mode
Indicates the mode in which the shadow
is removed. The shadow generated when
objects are moving affects the detection
size. Set this parameter based on the site
requirements.
NOTE
– The parameter can be set to low, medium,
and high. You can set the parameter based
on the shadow strength.
– In a scenario with no shadow or small
shadows,
Weak shadow
is recommended
to ensure complete detection of objects.
– In a scenario with large shadows,
Strong
shadow
is recommended to cut objects
from shadows to make bounding
rectangles closer to the object sizes or cut
objects with shadows between to
separately display the objects.
Detection sensitivity
Indicates the sensitivity in which an
object can be detected.A higher
sensitivity indicates a higher
identification rate but also a higher false
alarm rate and more device performance
occupied.
NOTE
– The parameter can be set to low, medium,
and high. You can set the parameter based
on the site requirements.
– When there are many obstacles such as
lamplight and rustling leaves,
Low
is
recommended to prevent false alarms.
– When the foreground and background are
of the similar color,
High
is
recommended.
Background update rate
Indicates the speed of integrating an
object into the background. A large value
indicates quicker object integration.
NOTE
– The parameter can be set to low, medium,
and high. You can set the parameter based
on the site requirements.
– If the moving speed of an object is slow
and the background is clean, you are
advised to set this parameter to low.
Otherwise, the object may quickly
integrate the background, which is inferior
to foreground extraction.
– If the moving speed of an object is quick
and there is no external interference, you
are advised to set this parameter to high.
