In this paper, a method for generating  structural descriptions of
stereo image pairs and their matching to recover 3-D form of objects 
in space, is discussed. The method consists of the following steps:
firstly, straight line segments are extracted in both images and the
relations among them are investigated. The relational subgraphs are 
constructed then, and the correspondence graph is created. Using the
"stable marriage" searching algorithm the features in one image 
corresponding to features in the other image are found. The method was 
tested on a set of aerial stereo images of urban scenes.<p>
