I'm working in a computer vision project, where the goal is to detect some specific parasites, but now that I have the images, I noticed that they have a watermark that specifies the microscope graduation. I have some ideas of how to remove this noise, like detecting the numbers and replace for the most common background or split the image but if I split the image I'll lose information.
I would like to hear some recommendations and guidelines of experts.
