Track grouper

摘要

There is provided a method for tracking a group having at least two targets. The method may comprise selecting the at least two targets from a plurality of targets. The at least two targets may be selectable based upon their respective target datum thereof. Thereafter, a dual gate surrounding each respective one of the at least two targets is defined, wherein a movement of each dual gate is synchronized with a movement of respective one of the at least two targets corresponding thereto. The dual gate of each respective one of the at least two targets may then be associated with each other to form the group.
