We address the problem of blind multichannel image restoration using multiple FIR lters. Previously, we have extended the 1-D mutually referenced equalizers (MRE) method for blind equalization of multichannel FIR system to the multichannel image restoration problem. In this paper, we present further results of a new version of 2-D MRE method that is more robust against additive noise. Compared to other restoration methods using multiple FIR lters our method is computationally more e cient, since the size of the matrix in the algorithm depends only on the size of blur and restoration lters and not on the image size. Finally, simulation results are presented in order to demonstrate the restoration results using the 2-D MRE method, which we compare with the least-squares (LS) method.
