De-Striping Sidescan Sonar Image

Discussion created by 8556732 on Oct 21, 2013
Hi,

I've got a raw sidescan sonar image, with regularly spaced stripes at 45 and 135 degrees respectively (NE-SW, and NW-SE).

After extensive searching I'm aware that I need to apply some kind of directional fast fourier transform (FFT) to the image to remove the stripes.

Only thing is I have no idea how to do this in ArcGIS!

The image is provided as part of a PhD dataset; I need a nice DEM to work with. At the moment I cannot quanitatively use the DEM for anything, as the stripes add error!

I will also add that the image is quite large, and was exported from a .dat in SMT Kingdom and re-gridded in Arc.

Thanks

Kieran
