[Micha Silver]

Did you try the grass smoothing tool, v.generalize?

To limit the pixelation of this cover, I was thinking of smoothing the layer with the QGIS tool. This works, but the problem is that it generates topology/geometry issues (overlap, holes, etc.). And I can't afford to have invalid geometries. Could you share some advices? Guidances in order to skip those problems? I've attached a screenshot of the smoothed vector segmentation.
