human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "optimizing for aesthetically pleasing quadrotor camera motion"):
  Abstract: We propose an algorithm that optimizes positional and temporal reference fit jointly to generate globally smooth quadrotor camera trajectories. Videos are perceived as better looking than results of the state-of-the-art.

Includes members:
  Member "wyfiwyg investigating effective user support in aerial videography":
    also connected through other hyperedges:
      (none)
  Member "automated cinematography with unmanned aerial vehicles":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "cinemairsim a camera realistic robotics simulator for cinematographic purposes")
  Member "airways optimization based planning of quadrotor trajectories according to high level user goals":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "cinemairsim a camera realistic robotics simulator for cinematographic purposes")
  Member "towards a drone cinematographer guiding quadrotor cameras using visual composition principles":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "autonomous aerial cinematography in unstructured environments with learned artistic decision making")
