摘要：
We consider segmentation of geo-spatial images by Markov random fields. MRFs whose distribution is specified by the Kullback-Leibler divergence between class-conditional densities are introduced for the spatial model. It is shown that the model is a natural extension of Switzer's assumption, and the estimation method of the parameters is established by maximizing the pseudo likelihood. The method is applied to benchmark data, and it shows a good performance.
