How to batch remove watermark from an image?

Question

C++ / C#

Hello toaster. Perhaps you will not understand me, because I encroach on someone else's, but a hungry and poor programmer also needs to somehow earn for himself. The question is to write a program that would batch remove the same translucent watermark from an image.
Please advise algorithms and libraries for this in c++.

Helps with batch processing.
First, find/draw the original watermark.
And add / multiply / subtract (here you need to experiment) with the processed image.

Answer 2

Why write this when there is already Photoshop and it can process it automatically and in batches? there are actions

Answer 3

it's good that watermark is not the only means of copyright protection
