• Depth noise lter level
: An analytics mechanism lters out unreliable depth correlation
data in cases where homogeneous surface or periodic pattern scene exist. Chances
are it may be impossible to ignore these regions because objects may still pass through
these regions.
• When to consider increasing the Depth noise lter level?
Sometimes, the floor itself may consist of homogeneous surface or patterned
materials. In such cases, it is not possible to draw exclusive regions to get rid of
these regions because the moving object will inevitably pass these regions.
The Depth noise lter level is useful when you need to suppress the interference
from homogeneous or patterned surfaces on the floor. Increase the level to
suppress possible interference. However, if the level is too high, the depth
information of moving objects may also be suppressed, resulting in the chance of
losing objects' movement tracks.
If the interference is very signicant and the Depth noise lter level must be set to
a higher value, try increase the Sensitivity level to reduce the possibility of losing
object tracks. You can check if the Depth noise lter level should be increased. For
example, the Depth view video shows signicant ickering white noises in the oor
area.
Object trajectories are likely to be trapped in these regions
