35 Operation and settings
> Pink box (Minimum pixel size) : This option determines the minimum size of
the objects to be filtered among the final detection results. (Display pink box in
preview)
Perspective filter
For certain video analytics, use the perspective filter function.
If you select this option, the blue and pink box is displayed on the preview window.
Click on the edge of a box and drag it larger or smaller as required. Click on the other
edge of the box and drag it larger or smaller to resize it appropriately.

tive plane.
> Blue box (Mini size polygon): This option determines the minimum size of the
objects to be filtered among the final detection results.
Basic Parameters
Basic parameters are direct related for the video analytics.
Object Detection
> Detection sensitivity: Select the sensitivity to detect the object. If this option
is set as relatively high value, even a slight local change in the scene will be
detected as an object and vice versa.
Object Tracking
> Strictness: Select the strictness for object tracking. If this option is set as
relatively low value, system will track objects even though the similarities of
objects between frames are low and vice versa.
Advanced Parameters
For more detailed parameter settings, use these options.
Object Detection
> Detection sensitivity: Selects the sensitivity to detect the object. If this option
is set as relatively high value, even a slight local change in the scene will be
detected as an object and vice versa.
> Grouping sensitivity: Selects the grouping sensitivity for the degree of ‘object
grouping’. If this option is set as relatively high value, local changes which are
proximally positioned in the scene will be grouped as one object and vice
versa.
Object Tracking
> Strictness: Selects the strictness for object tracking. If this option is set as
relatively low value, system will track objects even though the similarities of
objects between frames are low and vice versa.
> Search Range: Selects the search range of ‘tracking’. If this option is set as
relatively low value, system will search the small range of region to track the
objects in next frame and vice versa.
> Count for withdrawal: Selects the time to make decision for object’s withdrawal
in the scene. If this option is set as relatively low value, system will decide the
withdrawal of objects in small amount of time and vice versa.
