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.

Modern Image Processing Algorithms Implementation in C
It looks promising.
I like the way each algorithm is explained with minimal example and demo images.
I'm looking for such a lightweight vision lib to embed simple image manipulation programs on tiny ESP32-CAM boards.
OpenCV seems too heavy to integrate on such small devices.
So far, I've been able to develop simple image processing programs with CImg[1] (simple filtering, image cropping, adding text).
I'll try to spend some time exploring this SOD lib, thank you for sharing.

Plain Text. With Lines
Congratulations, now you replaced a trivial file format that (from a quick glance at the code) needed about ~35 of easily readable and self-contained Lua code to parse with an external dependency that would be much larger and harder to follow and either having (at least) an XML parser as its own dependency or implementing its own XML parsing, as well as being at the mercy of their developers. Also unless you are using some highly popular library, you may end up with some abandoned dependency.
Examples of both are at [0] (C++ based parser, you'd also need to write some bindings for lua) and [1] (Lua based parser for a subset of the format, abandoned for almost a decade).
There are times when using an external dependency might be a good idea, but a text-based file format that describes lines and can be implemented in a few lines of code is not one.
What are some alternatives?
