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 "detection and estimation of iris centre"):
  Abstract: Detection of iris center is an active area of research in the field of computer vision and human-machine interaction systems. The major issues involved in the detection of iris involves glint on the corneal region, occlusion of the iris by eye-lids, occlusions due to eye gaze, high speed of processing etc. This paper presents an algorithm for detecting and estimating the iris center thereby addressing some of these issues.

Includes members:
  Member "a vision based system for monitoring the loss of attention in automotive drivers":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "image based eye gaze tracking and its applications")
  Member "a video database of human faces under near infra red illumination for human computer interaction applications":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "image based eye gaze tracking and its applications")
