BoofCV

Unsure if the authors are aware of the connotation, but among drug users, the term "to boof" and "boofing" refer to intra-rectal administration of drugs.

I thought that was mildly amusing. I'm not sure if it's funnier if they are, or aren't.

I wanted to flag this library up because I haven't ever seen that much chat about it – but I've used it for a couple of years for several computer vision projects, and it's been a really good experience. Found it to have decent documentation and a thoughtful design. It's got a smaller feature set than OpenCV, but in my experience is more ergonomic.

I initially picked it up because I had a project involving QR code recognition that needed configurability and high throughput, and just happened to stumble across the demo app – https://boofcv.org/index.php?title=Applications#Examples_and... – really good example of how to showcase library features, and I totally recommend downloading and just seeing how it works if you've got a passing interest in CV.

This is an awesome (pure?) Java library I already used for some of my projects (e.g. for a Multi-JPG to PDF converter with book edge and finger detection). It offers basic things like thresholding, sharpening and edge detection as well as more complex stuff (video object tracking, etc.).

It is pretty fast (although it is Java) and easy to use (well documented with examples). There is also a Demo android app in the play store, where you can take a good look at the features.

There's also a Clojure wrapper for it https://github.com/boechat107/eye-boof

Interesting project. Is there any comparison with OpenCV in terms of quality and performance?
