Remote Sensing Image Change Detection Based onMulti-band Information Fusion

Traditional remote sensing image change detection methods have difficulty in detecting com-plete change information based on a single-band.To solve this problem,the paper proposes a multi-band remote sensing image change detection method using a Markov Random Field,fusing all bandchange information.In the process of solving the MRF model parameters,the MoLC(method of Log-Cumulants)and EM(expectation-maximization)hybrid model is introduced for iterative calculation.Experimental results show that the detection accuracy of the proposed method is superior to the cur-rent change detection methods,and is stable.
