摘要 在提高遥感图像分类精度的方法中,将纹理信息作为扩展的特征向量加入特征空间中,是一个很有效的方法。从地统计角度利用地物在空间上的联系提取纹理,进而参与分类,实验结果表明加入纹理后明显提高了具有纹理信息的地物的分类精度,并通过实验中遇到的问题探讨了该方法的适用范围。 In the methods of improving the classification precision of remote sensing images,adding textural information as an expanded eigenvector into feature space is a pretty useful method. In this paper,the author extract texture using spatial connections between geo-objects, then put it into the classification process. This experiment shows a nice result. Through the problems encountered in this experiment,we discussed the appropriate scope of this methodology.
