How can I find out which of the possible watermarks is applied to a particular image?

Question

Java

There are old images with the logo of the old site superimposed on it, you need to replace it with a new one. There are no original images.

There are watermarks themselves, their location too.

There are images where one watermark is in one place, another watermark is in another place, and there is a watermark that is on different images in the same place, but with different transparency.

Example:

Below are the watermarks themselves, the coordinates are available.

As I understand it, you need to use some algorithm to drive out images and watermarks, and in which case there will be a greater% similarity, that watermark is used.

Maybe there are ready-made libraries, algorithms?

Answer 1

If there are not so many images, then you can successfully solve the problem by manually editing in Photoshop.
