基于标点随机过程的遥感影像道路提取

Road Extraction in Remote Sensing Image Based on Marked Point Process

  • 摘要: 在分析贝叶斯方法用于遥感影像目标提取技术的基础上,基于标点随机过程方法,利用线状地物的整体几何约束和地物之间的空间结构及相关关系对目标构建数学模型,提取线状地物,并以道路网的自动提取为例,详细阐述了此算法。

     

    Abstract: Based on the Bayesian approach,this paper proposes a method to use marked point process to model the prior knowledge of the expected extraction object such as road network.The marked point process model cooperate the prior model and the image data to extraction the linear object in high-resolution remote sensing images.The whole process embedded into the simulated annealing algorithm.
