First time using OpenCV on C++ I've been using it with Python and I really needed a tutorial on how to do it with C++ Your tutorial is freaking great! Thank you so much and you definitely received a new subscriber & like on the video!

Ive been learning C++ for 7 years now, and this is the first time I saw anyone use "Exclude from project". All I did was comment, and it reached to thousands of lines of codes lol The tutorial is on point, informative and tackles everything I'll wish I know RE: OpenCV

In which field you are using C++.?

[@BTXSISTEMAS]

The best opencv tutorial i found on web !!! Congrats man !! Great job.

You are great. First time I see something very easy that many companies make it very complicated and they sell you expensive software that they cannot do it ....!!!

[@nkheart4]

when you try to separate square and rectangle at the chapter7 about 2:13:01 you will notice the big blue rectangle at the bottom it's not a square this is how to fix it when width is larger than height you should (height/width) to find the aspect ratio but when height is larger than width you should (width/height) instead

My heart broke when I saw Vectors and Matrixes passed by value and not by reference. I'd love it if the author explained the effect of each parameter in the functions it used, at least once at the beginning of the video, instead of "play with them to match your needs" Still great content. Thanks.

[@pretzelboi64]

Yeah, that's just straight up bad C++. Big data structures should always be passed by const reference if read-only.

[@jesuschrist1501]

video isn't about optimization, its to start off on the basics for those who are interested in opencv.

[@MichaelDuarte]

@@jesuschrist1501 This is just feedback for the creator, bringing it up in a nice way to a creator that has so many viewers can be helpful for following videos. It was just a matter of adding a single `&` to the parameters.

[@pretzelboi64]

@@jesuschrist1501 There's no point learning OpenCV if you're not willing to learn proper C++. The entire reason OpenCV was built with C++ is that computer vision is performance-critical.

[@ZizuZiomek]

@@pretzelboi64 It is shallow copy only, so it is pretty cheap operation (incrementing one counter, and copy small object)

in the first test code at 18:35, it shows up as Thread 1:signal SIGBART on my xcode, what can be the problem

[@DaDooM88]

Got some questions: 1) I know that you intention was just to introduce us to some functions and not create a perfectly logical program, nevertheless may I ask: if you blur with size (3,3) and then dialate with a 5x5 rectangle, dont you basically lose information? 2) did you maybe want to blur the gray-image instead of the unprocessed image (around 34:40)? Would that yield better results for edge detection?

[@DaDooM88]

ah you corrected your mistake at 1:41:15

[@DaDooM88]

And for everyone, its better practice just to include #include , as this will evaluate what modules were actually built.

(and use x64 opencv, and change properties for proper version (x64, release and debug)) 2) after editing environment variable 'path', you should restart computer (or at least log out/log in). If you don't like editing 'path', you can add path to Property->Linker->general->Additional Library Directories 3) if you download other version of OpenCV than 4.5.0 (i use 4.5.3), you should change Property->Linker->input->Additional Dependencies, to that from your opencv folder (i have 'opencv_world453.lib').
