Abstract:
A method for tracking a group having at least two targets, the at least two targets being selectable from a plurality of targets, the method comprising:a) observing the plurality of targets, each respective one of the plurality of targets having a target datum; b) selecting the at least two targets from the plurality of targets, the at least two targets being selectable based upon the respective target datum thereof; c) defining a dual gate surrounding each respective one of the at least two targets; d) determining a movement of each dual gate, the movement of each dual gate being synchronized with a movement of respective one of the at least two targets corresponding thereto; e) associating the dual gate of each respective one of the at least two targets with each other; and f) forming the group in response to the dual gate of each respective one of the at least two targets being associated with each other, the at least two targets being maintainable in the group as long as the association of the dual gate therebetween remains intact thereby facilitating continuity of the group.
