摘要
给出了一种新的阴影提取方法,根据阴影区域在InSAR相干系数图上的特性,利用Sigma滤波和最优阈值分割算法实现阴影的自动提取。实验结果表明,本方法是一种高效的阴影提取方法。
Shadow is a general phenomenon which occurs in SAR images, and it has many vital applications in various aspects. A new solution of shadow extraction is presented in this paper. By Sigma filter and optimal threshold segmentation algorithm, Shadow can be extrac- ted from InSAR coherence. Both the theoretical analyses and the experimental results indicate that the proposed method is a highly efficient method of shadow extraction.
