A tracking system that may initially take image sequences from sensors and regions of interest computed automatically, or defined by the operator, or provided by another approach or way. Tracklets may be initialized from the provided regions of interest. The tracklets of the same target may be associated with each other to form another tracklet of another level. Tracklets may be merged to form tracks. Association of tracklets or tracks may be effected at various levels in a hierarchical manner. Also, association of observations, tracklets and tracks may be based on a computation of distance, i.e., similarity in motion and appearance.
