How to add scan effects?

Question

Scanning

Tell me some project or tool, OR code, so that it can make a scan from the picture (add page edges, drawings, defects, etc.)
That is, we give an even picture at the input, we take the scan image at the output

Answer 1

There is a free service that applies a scan effect to JPG and PDF documents - https://makescanned.com/

Answer 2

Three problems:
It is done in 4 steps in any graphic editor with layers if you have the desired background (open the background, add the image as a layer, balance the brightness with the background, place it in the right place, export), you can screw the script with imagemagick convert (using all the same layers )

Answer 3
