[GRASS-user] creating custom filter with r.mfilter

GRASS GRASS user

Any working code I can start with to create custom filters? I
basically want to run the speckle filters in GRASS. Sample filters
are explained here:

I have implemented a SAR Speckle Filter module, uploaded
right now to GRASS 6 Addons. For now only the
GAMMA SAR Speckle Filter is implemented.

Installation:
g.extension i.despeckle

Please expand with other filters (Lee, Frost etc.)

I forgot to mention that there is a screenshot example
with PALSAR:
