【Abstract】 The random field models are effective in synthesizing the natural texture according to the statistical distribution of intensity of texture in space. The generalized longcorrelation(GLC) model, which can be used to synthesize more kinds of visible texture than the Markov random field(MRF) model, is a model introducing the parameter of correlation length based on the MRF. The infrared texture can be produced by reconstructing the gray distribution on the visible texture according to the distribution of the temperature field of the terrain in space.更多还原
