Does anyone know how to delete single edge pixels in a raster after a mask is completed?

I could convert to polygon and back to raster, but I don't want to lose accuracy. I am using ArcMap.

  • Try region group, it will contain count of pixels. – FelixIP Feb 14 '20 at 19:36
  • Feel free to ask a separate second question about ArcGIS Pro if you want to know how to do it in both applications. – PolyGeo Feb 14 '20 at 19:59
  • You should be able to apply some filter, for example convert to numpy array then: stackoverflow.com/questions/46043048/… – BERA Jul 28 '20 at 9:30

Does these pixels all has the same unique value? for example, 0,0,0? You can just omit those pixels from your raster.
