在这封信中，我们调查了共生纹理测量的使用，以提供关于城镇结构内不同建筑密度的信息。我们试图通过将纹理度量作为块分析和分类的一种手段来改进城市区域的逐像素分类。我们发现了一些关于纹理度量要考虑的窗口的最佳维度以及最有用的度量的有趣提示。此外，我们还表明，可以使用易于获得的中等分辨率卫星合成孔径雷达图像进行比先前显示的更精细的城市分析。
In this letter, we investigate the use of cooccurence texture measures to provide information on different building densities inside a town structure. We try to improve e pixel-by-pixel classification of an urban area by considering texture measures as a means for block analysis and classification. e find some interesting hints concerning the optimal dimension the window to be considered for texture measures, as well as the most useful measures. Moreover, we show that it is possible to use medium-resolution readily available satellite synthetic aperture radar images for a more refined urban analysis than previously shown.
