Use of PVM for MAP image restoration: A parallel implementation of the ARTUR algorithm

Markov Random Field (MRF) based algorithms used for restoring images affected by blur and noise are generally very effective, but most of them are computationally very heavy. The recently proposed ARTUR algorithm is a deterministic method that belongs to this family. In this work, a parallel impleme...
