speckle noise
Hi,
I have to remove the speckle noise from SAR images. Can anyone suggest me which is the best method to remove it.
Regards
Shaaminy

It seems to me speckle noise is (diffractive?) interference signal, thus very high spatial frequency. I think the best method is just spatial filter, e.g., cut off in frequency domain.

Do a search for the well known Knox-Thompson method for speckle
reduction:
