Partial motion trajectory grouping through rooted arborescence

A novel method is presented for trackingmultiple deformable objects in a multiview scenario. We avoid applying fixed constraints of object sizes for object isolation, but guide the splitting/merging of objects by grouping partial motion trajectories extracted from the occupancy status of objects in the homography ground-plane. We treat this clustering task as solving a rooted arborescence problem, and investigate the performance of the proposed method by experimental results.
