Network Flow Method Integrates Skeleton Information for Multiple Tracking.

In order to solve the issues arising from collisions, this paper proposes a network flow method combined with skeleton information for multiple tracking. In the intra-track stage, non-colliding are identified and associated as trajectory fragments based on their motion and positional information, and colliding are then segmented based on an improved skeleton algorithm and matched as trajectory fragments. Subsequently, the trajectory fragments are employed as vertices to construct a network flow model.
