| 摘 要： | 针对传统高分辨率遥感影像变化检测方法大多直接利用光谱信息进行计算,导致检测精度不高的缺陷,提出了一种基于条件随机场模型(CRF)的高分辨率遥感影像变化检测方法。该方法利用CRF模型融合差值影像的光谱项和空间项,在融合过程中,引入EM迭代策略不断更新影像检测结果,提高变化检测精度。试验结果表明,本文方法的分类精度好于传统方法,并且稳定性良好。

| 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. |
