Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

JDK 21 - Image Performance Improvements
Is there any fast way to get pixel values and pixel coordinate? I had to jump through a lot of hoops to get convert BufferedImages into a format that's useful for image processing it to be a reasonable speed in BoofCV. getRGB() is glacial. At one point I was trying to convince the JDK team to make private data structures public again. Right now it's inconsistent what you have access too.

Good Open Source Repositories that Accepts New Contributors
Speaking of using the vector api, I see there's a class in boofcv that converts rgb to hsv. I've previously written a simd accelerated version of rgb to hsv using the java vector api. For anybody looking to do a bit of code janitor work, converting the one-off library into something that could be contributed to /u/lessthanoptimal's project might be a worthwhile contribution.

JavaFX .jar (from clojure) won't find "glass" when run via `java -jar`
For instance I looked at BoofCV and all I found was : https://github.com/lessthanoptimal/BoofCV/issues/265 " the question now seems to be can you compile the library as native. The answer is probably but someone needs to try it."

Tesseract OCR
Image processing strongly depends on what image you wanna use. To find an "auto" approach, that works for every image is nearly impossible...
I once wrote a bookscanner app in Java (https://boofcv.org), where everything was done automatically (preprocessing, object detection / book extraction, skin detection / finger removal, deskewing, line-slope-correction and so on). It was very difficult to adjust the parameters, that at least most of the books looked good.
- Does anyone know of an open-source library that not only has object-detection but also object following?

JEP proposed to target JDK 18: 417: Vector API (3rd Incubator)
Neat, that's been my results as well (rgbhsv conversion library). Are you planning on updating your readme with your latest benchmarks? I'd be interested to see if you're getting closer to the advertised 24 GB/sec of the c++ library.
