街道级地理观测器的开发是近年来一个非常活跃和具有挑战性的研究课题。在这种情况下，窗口的检测、表示和分类对于识别相应的立面是有益的。本文提出了一种新的窗口和立面检索方法。该方法基于等高线图的相似性，引入了一种新的图核来进行不精确图匹配。我们设计了一个核相似性函数的结构化集的轮廓，这将考虑到结构集内的轮廓方向的变化，以及空间接近。然后，我们能够提取窗口作为立面图像的所有轮廓的图的子图，并从立面图像的数据库中检索类似的窗口。
The development of street-level geoviewers become recently a very active and challenging research topic. In this context, the detection, representation and classification of windows can be beneficial for the identification of the respective facade. In this paper, a novel method for windows and facade retrieval is presented. This method, based on a similarity of graph of contours, introduces a new kernel on graph for inexact graph matching. We design a kernel similarity function for structured sets of contours which will take into account the variations of contour orientation inside a structure set, as well as spatial proximity. Then we are able to extract a window as a sub-graph of the graph of all contours of the facade image and to retrieve similar windows from a database of images of facades.
