Assuming that I've not misunderstood, how does this compare to things like: TrID [0]?? Apart from being open source. [0] https://mark0.net/soft-trid-e.html. - Source: Hacker News / 3 months ago

If not, try using something like trid to detect what the file is, and other tools like ffmpeg or imagemagick to see if they can read it. Source: 12 months ago

.vi is not a file extension commonly associated with any common video format. The closest I can find is that it's an Arcsoft VideoImpression Project file, which may or may not contain actual video data. This is their website but from what I can find the VideoImpression product is discontinued. You can use TrID on the file to see what it thinks the file type is based on its magic number.

You can try to use some tools that detect what extenstion file should have based on the content of the file, if the file is small, you can try https://www.checkfiletype.com/, otherwise you can try this tool: https://mark0.net/soft-trid-e.html. Source: about 1 year ago

If file isn’t working (extensible as mentioned) you could try TRiD. 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: over 1 year 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
