Acceleration of RED via Vector Extrapolation

  title={Acceleration of RED via Vector Extrapolation},
  author={Tao Hong and Yaniv Romano and Michael Elad},
Models play an important role in inverse problems, serving as the prior for representing the original signal to be recovered. REgularization by Denoising (RED) is a recently introduced general framework for constructing such priors using state-of-the-art denoising algorithms. Using RED, solving inverse problems is shown to amount to an iterated denoising process. However, as the complexity of denoising algorithms is generally high, this might lead to an overall slow algorithm. In this paper, we… CONTINUE READING
