Can remove watermarks from your images. It works well for images with text (i.e. scans etc) and the best result will be in case if watermark is black and white.

1. You need to create a folder with name images_for_restore in the directory where python files situated.
2. Put images in this folder. Be careful! Your images will be changed, so make copies of them before using program.
3. Go to website like https://imagecolorpicker.com/ etc. Your purpose is to get the lowest and the highest Red, Green and Blue values of your watermark. If it is colorful you may need to run the program a few times to delete all the colors of your watermark.
4. When you get values run the script.

You can try to use the script with non-text images, but 99% the result will be bad and your image will be just damaged, so the best way to use this script is text images.

Good luck!
