                         image information. When the edge detection is performed on range 
                         images it provides much more information than the edge detection 
                         based only on intensity images because range images have explicit 
                         3-D information. In this paper, we present a study of how to 
                         detect step and roof edges on range images, that, when combined, 
                         can be used, for example, to give an aproximate number of image´s 
                         regions. We also deve morfology based algorithm to perform 
                         thinning operation on the detected edges.",
