A good lecture to follow along I became interested in OPENCV, so I followed the lecture in C++, but I felt that VS 2013 and later versions were difficult to follow, so I came to the Python lecture. The lecture content was not long and easy to follow, so I had fun practicing. One thing that was disappointing, as I mentioned above, was that the lecture content was short, so it felt like I just pasted the code and left... I followed it, but I felt a lot of regret. I wish it had been a more expandable lecture, such as how to utilize it, but it ended after it was created, so I feel regretful.
