                         computationally efficient way. The motivation is the development 
                         of a new methodology for contextual classification that uses 
                         combination of sub-optimal MRF algorithms for multispectral image 
                         classification, which requires accurate parameters estimation. The 
                         results show that the method is consistent with real image data 
                         and in the presence of random noise.",
