[Question] Easiest way to detect ethnicity using OpenCV & C++?
As the title implies, I'm looking for the simplest way to detect race/ethnicity in a photo (or a frame by frame video, shouldn't big a big difference) using OpenCV (I'm using the opencv-contrib build) and C++. I'm a complete beginner.

I'm starting to get tired
Since you have C# experience, take this time to learn more about C++ while you continue to look. While yes, it is very easy to write bad code, it's not a huge deal since you just graduated and are just hacking around. Plus there are a lot of helpers these days to make writing bad code a little less likely.A former mentor of mine gifted me "C++ Without Fear" by Brian Overland which I can recommend. It's not too expensive, I think it was $25 or something like that, likely less used. Also comes in E-book form.If you'd like a gentler introduction to C++, may I recommend openFrameworks?

I know C++. What game engine should I use?
I recently heard of openFrameworks which should make it pretty easy to make your game. It handles putting together a bunch of other libraries and window management so you can focus on drawing some shapes on the screen and handling user input. Sounds like love2d but all C++.

Nannou – An open-source creative-coding framework for Rust
I mean, https://www.libcinder.org and https://openframeworks.cc have been mainstays of the creative coding industry for a long time now. A Rust take on the problem shouldn't be too surprising.
