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 "on nearest neighbors in non local means denoising"):
  Abstract: To denoise a reference patch, the Non-Local-Means denoising filter processes a set of neighbor patches. Few Nearest Neighbors (NN) are used to limit the computational burden of the algorithm. Here here we show analytically that the NN approach introduces a bias in the denoised patch, and we propose a different neighbors' collection criterion, named Statistical NN (SNN), to alleviate this issue. Our approach outperforms the traditional one in case of both white and colored noise: fewer SNNs generate images of higher quality, at a lower computational cost.

Includes members:
  Member "block matching convolutional neural network for image denoising":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "enhanced cnn for image denoising")
  Member "probabilistic non local means":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "patch redundancy in images a statistical testing framework and some applications")
  Member "gradient magnitude similarity deviation a highly efficient perceptual image quality index":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "subjective annotation for a frame interpolation benchmark using artifact amplification")
