. SAR images restoration:

SAR (Synthetic Aperture Radar) images are strongly corrupted by a noise called speckle.

To illustrate the difficulty of the problem, here are some slices takeb from SAR images furnished by the CNES.

Synthetic image:

Initial image	Speckled image ($f$)	Reconstruction (u+v)
Restoration ($u$)	Oscillatory component ($v$)	Segmentation
