Abstract为了提取并表示高分辨率遥感影像中的主干道路段,提出了一种多分辨框架下的平行活动围道模型的算法.该算法在活动围道模型原理的基础上,重新定义各能量项:采用抛物线做为道路段的先验模型,增加了平行性能量,并采用多分辨框架下的梯度做为外部能量.该模型的优化过程实现了道路的定位,得到的结果是平行抛物线的参数,实现了道路的矢量表示.实验结果表明,能有效提取高分辨率遥感影像中的主干道路段.
Other AbstractAn algor ithm of parallel active contour model based on multi2scale frame is pr oposed to extract and repr esent main road segments from high2resolution remote sensing images. Energies in active contour model are redifined as following: using parabola to model two sides of main road segments as a prior, adding parallel energy, and adopting gradients in multi2scale frame as exterior energy. Optimizing the model results in location the two edges of road which is represented as a vectorgraph by the parameter of parallel parabolas. Exper iment results demonstrate the algorithm. s effectiveness in extracting main road segments from high2resolution images.
