I have an old recipt with just barely visible letters. Scanning it using the available office multifunction printer / scanner was not a success, it was just unreadable.
The attached version is a photo taken using my phone and it's already better. How can I enhance this iamge so it's more readable?
Auto-levels didn't give a great result, and my other ideas to somehow make the blueish color of the font stand out more, were unsuccessful. But as I don't know things about image processing, that's not a surprise.
Any ideas or hints? TY!
