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 "object tracking in video signals using compressive sensing"):
  Abstract: Reducing the number of pixels in video signals while maintaining quality needed for recovering the trace of an object using Compressive Sensing is main subject of this work. Quality of frames, from video that contains moving object, are gradually reduced by keeping different number of pixels in each iteration, going from 45% all the way to 1%. Using algorithm for tracing object, results were satisfactory and showed mere changes in trajectory graphs, obtained from original and reconstructed videos.

Includes members:
  Member "on some common compressive sensing recovery algorithms and applications review paper":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "fingerprint recognition under missing image pixels scenario")
  Member "sparse time frequency representation for signals with fast varying instantaneous frequency":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "fingerprint recognition under missing image pixels scenario")
