I have 4 images, all with the same original background, every single one of them has writing somewhere in the picture, if compared 1 to 1, the only difference would be the writing, I wan't to extract the pieces of background from each of the images in order to build the whole background back.
Image:
if all the difference are substracted, it can be achieved the background without text (and no contant-aware fill):
What I managed to do, which is really bad and time consuming:
- Select -> Color range
- Select all color from text
- Select -> Modify -> Expand by 2 pixel
- Delete
- Merge all of them together
This will leave JPEG artifacts and also won't be a real substraction, there are probably a term for what I'm trying to do, but since I don't know how it is, I arranged this title.
