    • Abstract
  • 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 extracted from InSAR coherence.Both the theoretical analyses and the experimental results indicate that the proposed method is a highly efficient method of shadow extraction.
