Finally won the battle and managed to install opencv4 in my Linux machine.
Studying the opencv library now using C++.
I have done opencv in the past with its python and JS versions, but never in C++. C++ is actually its core.
I just want to better understand the core of the opencv’s library while learning more C++ coding at the same time. Many things I am currently helping out, like the ar.js/artoolkit library, are written in C++.
I felt more confident after the WebGL/GLSL I studied from some good Udemy courses. Also my previous python as well as the JS I learned here helped a lot.
I am also following a couple of courses about C++ in several platforms and it feels like I paid too much (even if I bought just one at the very lowest rate) - skipping A LOT of videos and pages!!!
