Abstract: A new approach to building extraction based on grouping the feature of the vertical lines of building object is proposed. Using it, the regions where building may exist are marked. A new template matching algorithm, which accounts for the dependencies between features of object, is presented. Tests show that the recognition system can save a lot of runtime, and yield substantial improvement over others for cluttered scenes and processing the partially occluded objects.

摘要： 提出了一种基于建筑目标的竖直线特征寻找图像中存在建筑目标区域的方法；考虑了目标特征的相互关系，给出了一种新的模板匹配算法。实验表明：利用该文提出的算法建立的识别系统与其它识别系统相比，大大减少了运算时间，有较好的抗噪声干扰和处理目标被遮挡问题的能力。
