Sylvester Tikhonov-regularization methods in image restoration

  title={Sylvester Tikhonov-regularization methods in image restoration},
  author={Abderrahman Bouhamidi and Khalide Jbilou},
In this paper, we consider large-scale linear discrete ill-posed problems where the right-hand side contains noise. Regularization techniques such as Tikhonov regularization are needed to control the effect of the noise on the solution. In many applications such as in image restoration the coefficient matrix is given as a Kronecker product of two matrices and then Tikhonov regularization problem leads to the generalized Sylvester matrix equation. For large-scale problems, we use the global… CONTINUE READING
