Anisotropic diffusion on complex tensor fields for PolSAR image filtering
Nan Xue, Gui-Song Xia, Liangpei Zhang · 2014
This paper addresses the problem of denoising for complex tensor image. In particular, we extend the anisotropic diffusion, also known as PM model (Perona and Malik, 1990) for filtering images based on PDE, from scalar or vector images to complex tensor ones and apply the new method to remove speckle noises of PolSAR images.
