If I remember correctly:

  1. We used a grayscale version of the image for all three channels.
  2. Applied ZSSR and EDSR to the same image.
  3. Then created a grascale map = (ZSSR-GT)^2 - (EDSR-GT)^2 where GT is the Ground Truth image. This means that positive values indicate pixels where ZSSR wins
  4. Normalized this map by it's max
  5. Used some spatial smoothing (maybe gaussian blur)
  6. Then take map * (map>0) and add to the green channel, and map * (map<0) to the red channel. (dont forget to clip to 0..1).
