Despeckle app no difference between lee and gammamap
When using the Despeckle application on a Sentinel-1 Stripmap SLC image, we observe very little difference between these parameters:
- Lee, radius = 3, number of looks = 3
- Gammamap, radius = 3, number of looks = 3
We expect a larger difference using those two different methods.
Reproduced on Windows binary package with OTB 7.
