Detailed Description

Uses a multi-stage strategy to associate clusters: (1) Project clusters to expected location based on motion field (2) Associate unique matches within overlap radius (3) Associate long-lived clusters within motion vector bounds (4) Associate closest if within lower of overlap and motion vector (5) Else assign new ID.
