| 摘 要： | 结合二维Wold分解技术来对遥感图像进行分割，将图像分解为确定性随机场和纯不确定性随机场，通过调整它们之间的比例关系，来加强纹理边缘，从而改善马尔可夫标记场模型对纹理边缘过平滑的现象．实验对城区目标进行提取，结果表明本方法的有效性优于纯马尔可夫随机场所采取的分割方法．

| Abstract: | The remote sensing image was segmented by 2 d Wold decomposition. The decomposition includes deterministic random field and pure indeterministic one. The latter was regarded as Markov random field model. By this decomposition, the construction of image was adjusted to have better segmentation compact. Result of segmentation was presented and compared. |
