#603 new enhancement

r.neighbors with an output reference map

Reported by: frankie Owned by: grass-dev@…
Priority: normal Milestone: 7.6.2
Component: Raster Version: 6.4.0 RCs
Keywords: r.neighbors Cc:
CPU: Unspecified Platform: All

Description

If r.neighbours accepted a reference mask to compute convolution only on non masked points, it could reduce significantly computing time on large datasets and/or large window sizes. Of course that could be done after the whole map computation, but computing time would change significantly. Note that this is different from having an ordinary MASK applied to the input map, because the input raster is not masked out at all at convolution time.
