     - There is a border effect in function of ROI size due to speckle filtering, either:
         - "bufferize" ROI raster and crop to non-bufferized ROI after filtering
         - include filtering in pipe before mosaic: how to deal with superimpose? Won't it have a border effect anyway if ROI is at the border of transect?
