opencv-python
Automated CI toolchain to produce precompiled opencv-python, opencv-python-headless, opencv-contrib-python and opencv-contrib-python-headless packages.
Extra stuff like type checking and annotations are definitely not the reason why python became that popular and widely adapted and used, but it certainly doesn't hurt to add and use them.
To be clear, I'm not expecting people to start adding generics to their quick hacked together Python scripts (in fact please don't do that). Instead, if you're building a library or maintaining a larger Python codebase, a lot of these start becoming very useful. A lot of the typing features I mentioned are already used by Python under the hood, and that a lot of Python developers just take for granted.
Case in point, the python-opencv (https://github.com/opencv/opencv-python) library has basically no types and it's an absolute pain to work with.
BTW thats a really good SO thread, thanks for linking it!

PySceneDetect
:movie_camera: Python and OpenCV-based scene cut/transition detection program & library.
thought the same thing and wrote this: https://blog.mixpeek.com/dynamic-video-chunking-scene-detect...
which uses https://github.com/Breakthrough/PySceneDetect
under the hood i'm sure it's the same ffmpeg method ;)

Project mention: Show HN: EyesOff – Alerts you when someone peeps at your screen | news.ycombinator.com | 2025-04-19
Hey, thanks for the feedback!
This is on the roadmap, along with gaze detection.
https://github.com/opencv/opencv_zoo/tree/main/models/face_r...
This model lets you upload a reference face and then matches to those in images. I think this allows for the "approved faces" function you mentioned.
I suppose a difficulty may arise when we run a few models at the same time, however there is probably a lot of room for efficiency on the table and thanks to the small model size we are already in a good place.
