Does anyone have a good recommendation for resources to learn a bit about computer vision? I don't want to go too in depth, but I'd like to learn the basics.

OpenCV (demos) are a good way to get started with "old-school" computer vision. For machine-learning kind of computer vision see for example https://experiments.withgoogle.com/collection/ai

If you know python, this is an excellent resource:

In general, I like Adrian's site but over the years he has been locking more and more content (even blog posts that used to be available in the site) behind his courses. Not that there's anything wrong with charging for knowledge (you know, teaching and getting paid for it), but it's a shame that things that used to be available, and of great quality, have been "pay-walled" somehow.

Another good resource is https://learnopencv.com/ . Again, good quality stuff, if you know your ways it tends to be enough[0] but it's also a big funnel to get you to but one of their courses.

[0] though Satya Mallick does hide a lot of complexity from the readers, and that bites you if you try to implement things on your own
