A new expression of multiscale likelihood ratio is obtained. Algorithm fuses residuals produced by MAR model and gray value information of coarse scale image. It increases the distinction of different targets, in the meanwhile, segmentation is precise. The use of window in the pixel-by-pixel classification makes the method insensitive to noise and robust. Experimental results demonstrate that the method performs fairly well. %K Multiscale Likelihood Ratio Test %K Markov Property %K Image Segmentation
