Road extraction from the satellite images can be used in producing road maps as well as managing and developing geospatial databases. In this work, the extraction of roads from SPOT satellite images using artificial neural network has been studied. Then the location of tunnel is extracted from image using digital elevation information. Also it is tried to enhance the precision of the road extraction method using spectral information as well as texture and morphology. The method was implemented on SPOT satellite images of Tabrizand Miyaneh (Iran). The results of this research indicate that it would be possible to promote the precision of road extraction by using texture and morphology in image classifycation using neural networks. Finally the location of tunnel was extracted by digital elevation information. Junctions of roads and mountains have high potential in locating the tunnel. For this reason, in this study, the junctions of roads and mountains were also detected and used.
The study of complex networks had developed over the years to
include systems such as traffic, predator-prey interactions, financial market,
and even the world wide web. Complex network studies encompass biology,
chemistry, physics, and even engineering and economics [1-6]. However, the
dynamics of such complex networks are yet to be understood fully [7,8]. In this
paper, we will be focusing mostly on the possible learning ability in a complex
network. To do this, an optimization process is used via Wiener process [9,10].
It is apparent from the sample lattice shown that the final position was not a
basis of the transition probability, or it was never used to calculate the
probability, since the transition probability only considers the current
position. The final point is reached because of the orientation of the edges,
where each edge is facing the final point, an aspect of the nervous system (afferent
and efferent nerves) [11-13]. No matter how random the orientation of the
neurons is, each directs to the central nervous system for processing and is
transmitted away for reaction.
