I would like to hide an empty area of a panorama stitched with hugin (using the GIMP). Hide in the sense of blending it in unobtrusively. I.e. fill the area with the average color of the surroundings and blur it. Or manually smudge the surroundings into the empty area.
Is there a filter/plug-in that automatically smudges/blurs the edges into the area?
Not looking for seam carving. Thanks.
