Road Extraction from High Resolution Remote Sensing Image Based on Hough Transform

Hough transform method is robust in straight road extraction from high resolution remote sensing images. This paper uses the technology optimization of Hough algorithm for image segmentation based on connected domain extraction, the curve of the road and complex scene in Matlab environment, the experiment proves that the improved algorithm can effectively extract the road edges in com-plex scenes, reduce the number of parameters, improve the computing speed Extraction effect.
