A Dual Method for Uniform Noise Removal Base on L[infinity] Norm Constraint
Xin Liu, Zhibin Chen, You‐Wei Wen · 2017
In mathematics, the problem of uniform noise removal can be formulated as a minimization problem with L∞norm constraint. The key to solve the minimization problem is to find an efficient scheme to handle the numerical difficulty due to the property of the non-differentiability of L∞norm. In this paper, the dual problem for minimization problem with L∞fitting is shown and the solution of the dual problem is obtained by applying forward-backward splitting method. Our experimental results show the proposed method is efficient.
