航空影像中居民地的半自动采集

在围绕面状地物居民地的采集。利用高斯模糊处理提高影像上居民地区域纹理特征一致性的同时，通过灰度共生矩阵提取了纹理，用区域生长和形态学的方法全方位腐蚀与膨胀，完成了面状地物居民地的提取，并进行了矢量跟踪，通过对矢量结果分析，准确率达到90％以上。可以直接应用到GIS中去。

Semi-Automatic Habitation Collection in Aerial Image

As to the collection of the area tround feaure such as this paper introduses a successful way to that aim by two steps.Firstly .we take advantage of Gauss blur to enhance the consistency of the area ground feature textrue in the image.and extract the featrure by accrction Matrix at the samc timc.Then we etch and dilate the whole image with the methods of morphology and area growth..After vecor tracking of the image.we analyze the result and found the accuracy ratio can be above ninety percents.which proved that the way we refered above could be used in GIS.
