I am working with vectorized greyscale images converted into polygon layers by the QGIS vetorize tool. Currently I am using a rather long way to get rid of small polygones.
I convert the polygons into lines, run the Generalizer Tool (Plugin) with the Alghorithm "Remove small object" and a Threshold of 2.0 and convert the hole thing back into polygons.
Is there a way to do the same thing without converting the polygons into lines? I tried the v.generalize, but it does not seem to have the same Alghorithm for small object removal.
