【Abstract】 Aiming at the problems that the traditional watershed segmentation algorithm has over-segmentation and a large amount of computation in the process of road information extraction from remote sensing image,a watershed improvement algorithm based on threshold marker is proposed to obtain effective path image information from remote sensing image. The experimental results show that the proposed method can effectively avoid the influence of pseudo-minimum value on image processing,reduce the repetition rate of calculation and effectively extract the road information from remote sensing image. The research on road information recognition and extraction algorithm from remote sensing image has wide application value and academic significance.更多还原
