Abstract: For the traditional high resolution remote sensing image change detection methods mostly using spectral information to calculate directly,thus the accuracy of the detection result is not high,this paper proposes a high resolution remote sensing image change detection method based on conditional random field model(CRF).The method fuses the spectrum and space of difference image with CRF model,in the process of fusion,introducing the EM iterative strategy constantly updated the detection result,improve the change detection accuracy.The experimental results show that the classification accuracy of this method proposed in this paper is better than the traditional method,and having good stability.

Key words: high resolution remote sensing image, change detection, CRF model, Iterative calculation
