Abstract
A method, computer program product, and machine vision system for monitoring an activity area proximate an actuated passageway for the occurrence of an object-related event. The activity area includes a first activity zone and at least a second activity zone. The first and the at least a second activity zones are essentially parallel to the activity area. The actuated passageway is actuatable with a control signal. The occurrence of an object-related event is detected within the activity area. If the object-related event occurs within the first activity zone, a first algorithm is executed to generate the control signal. If the object-related event occurs within the at least a second activity zone, a second algorithm is executed to generate the control signal.
