Border Issues

As objects come into and out of the view of the camera their shape will not be correct. During that time the objects may be mistaken for something else.

To prevent this from creating false object detections we need to eliminate objects that are touching the border of the image. We can do this using the Blob Filter module that allows us to only select/preserve objects that avoid the border. The attribute "Location->Avoids Border" which eliminates any objects that are touching the border is added to the Blob Filter criteria. We also use this module to remove any objects smaller than 100 pixels which will help to reduce any noise objects caused by flickering lights or reflections from other moving objects.
