Abstract :
The design of a multichannel IIR restoration Wiener filter which incorporates the interchannel correlations is dealt with. The filter is based on multichannel autoregressive (AR) image modeling. This filter can be implemented easily in the spatial domain with low computational cost. Its performance is good
