In an effort to restore them as much as I could, I used a combination of waifu2x ("Single-Image Super-Resolution for Anime-Style Art using Deep Convolutional Neural Networks"), Clip Studio Paint resize/cleanup tools, and manual cleanup done by hand. Unfortunately, the red text on the title page was a lost cause. If anyone can decipher solid red rectangles please contact me lol. Source: about 1 year ago

Maybe this would help. There's also an app version of it. Source: over 1 year ago

Through the use of a public domain program (ImageJ), I was able to extract different information from the image. Source: almost 2 years ago

All my users get ImageJ[https://imagej.nih.gov/ij/]. Depending on needs, they can also get OsiriX, microdicom, or training on pydicom or matlab libraries. Source: almost 2 years ago

The tool in question is called ImageJ. It's an open source piece of image analysis software, commonly used in biology for processing microscope images. It can do stuff like hyperstacks -- more than two dimensions, such as x,y, z (a microscope that scan vertically), t (time), c (multiple color channels). Source: about 2 years ago

I used an open source program called ImageJ that lets you measure things is a bunch of different ways. I took one measurement as a reference then used the program to figure out everything else. Source: almost 3 years ago
