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 "two view constraints on the epipoles from few correspondences"):
  Abstract: In general it requires at least 7 point correspondences to compute the fundamental matrix between views. We use the cross ratio invariance between corresponding epipolar lines, stemming from epipolar line homography, to derive a simple formulation for the relationship between epipoles and corresponding points. We show how it can be used to reduce the number of required points for the epipolar geometry when some information about the epipoles is available and demonstrate this with a buddy search app.

Includes members:
  Member "epipolar geometry based on line similarity":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "an epipolar line from a single pixel")
  Member "fundamental matrices from moving objects using line motion barcodes":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "an epipolar line from a single pixel")
  Member "camera calibration from dynamic silhouettes using motion barcodes":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "probabilistic inference for camera calibration in light microscopy under circular motion")
