Ignore Zone Tab
The Ignore Zone feature is used to define up to three specific areas of an image
where no video analytics will be applied.
Important:
Any zone marked to be ignored applies to ALL alarms within that MSF.
Possible Usage:
The detection algorithm also detects and tracks subjects outside the detection
zones for improved detection when the subjects enter the zone. Some scenarios
include a high-level of activity that is not related to the desired detection, such as
a road located far from the zone. The ignore zone allows the system to ignore this
area and reduce the computational load for the algorithm.
An ignore zone may encompass a part of a detection zone, when the activity
inside that part is meant to be ignored.
Setting an Ignore Zone:
Drawing tool:
Polygon
button.
The
Eraser
button. This button is used for deleting ALL ignore zones.
Used for undoing the last performed operation (only the last action).
When setting an alarm, select the
Ignore Zone
tab and draw a polygon.
When the polygon is complete, it is filled by a hatched pattern to distinguish
it from a regular detection zone. Up to three separate Ignore Zones can be
created.
Use the
Undo
button to undo the last polygon edge drawn.
