Thanks for the screenshots. In my opinion, it isn't doing very much to eliminate the halos, but it is detrimentally affecting the image. The dehaloed are more dull, less shiny, less detailed and sort of look like looking through dirty glass. The raw images are better. I can live with the halos much more than the aliasing so it is not worth ruining the crispness and 3D pop to the picture to eliminate the halos. Maybe there are other methods that work better. If it could be combined with the edge detection, that might help. The halos tend to happen at the edges of the objects.
