Spot Stray Pixels

Hey, I thought it would be a good idea to add a feature that can detect pixels of one colour that are surrounded by pixels of other colours, this way we would be able to easily reduce the noise and work faster on it. Thanks!

I have a couple of ideas (that might be related to this one). It looks like there is a necessity of:

  1. Add outlines
  2. Remove outlines
  3. Add dithering
  4. Remove dithering (this one)
  5. Add antialiasing
  6. Remove antialiasing

Antialiasing example (a tool to add extra pixels to reduce aliasing):
