In this paper we present a method for generating  and matching 
structural descriptions of objects from stereo images. 
It consists of the following steps: firstly, straight 
line segments are extracted in both images and the relations 
among them are investigated. Secondly, the relational 
subgraphs are constructed and the correspondence graph is 
created. Finally, using the graph theoretical "stable marriage" 
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>
