You are blowing smoke.
I don't know why, but you are blowing smoke. You previously challenged me with an AP image where these signatures were rendered with identical sized pixels. I said that this could easily be done and I presented an image where I demonstrated this.
You continue to suggest with different words this time ("many processing options" and "thresholding") that it is easy to produce an image of the sort the WH produced that is not a composite. I say: Deliver or Disappear from these threads.

If you be so kind, please ping me to these threads since that would save me the trouble of searching for them.
