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

[@amazlin8271]

In which field you are using C++.?

[@tilerderden778]

Учусь на первом курсе Самарского университета, вот захотел выучить фреймворк, почти все без проблем получилось, с чем-то буду лучше знакомиться. Очень интересно и понятно, спасибо автору. P. S. я хочу, чтобы русские комментарии тоже были здесь

[@tango-rp1rk]

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 ....!!!

[@BTXSISTEMAS]

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

[@thiagosoares5052]

bro, I'm from Brazil and I'm thanking you immensely for this content, from your channel, despite not speaking fluent English, I didn't find any content like yours in Brazil....

[@teezhenquan5855]

Hi, can you do more projects on opencv with c++. For example, like basic people counting system

[@leannviolet]

Every time I need to set up windows for openCV - this video is literally the only one I find useful, I come back to it every time

[@sayantansinharay9161]

I would be very pleased if you make more videos in C++. CP guys need it. :). Please make more videos on C++.

*I need to learn OpenCV for my bachelorthesis/-project* Me: "Sweet! There is a channel with perfect videos for my needs in python!" My Prof: "You need to learn OpenCV with C++" Me: "NOOOOoooooo!"

[@StyleClubDetailing]

Hello! Thank you so much for lesson's course of OpenCV! Very, very interesting and informative course, which helped me a lot! Thank you very much! Keep it up!

[@gareven]

I have been looking for a good OpenCV in C++ explanation video all over the youtube, and this is the best one I have found so far!!! thank you!

[@Protoman00]

Thank you so much for this video! This video helped me finish my senior project and graduate!

[@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

[@MethodiusOgolkov]

Thank you very much for the clear lesson on this topic) I am a schoolboy from Russia and my English skills are not very good, but I understand what you are talking about! Thank you for such simple and detailed explanations!

[@MichaelDuarte]

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)

[@ayu_rdjroot]

wow! sooooooooo-- thank for your course! It is really really give me some help for my learning! I will recommend your course on my technical blog in China so that more people can see it!

[@glitchgatsby4290]

Binge-watching this like it's a new season of some show I like on Netflix.

[@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.

Try placing the info file in the folder where your .xcode file (for your current project) is contained. This might not work the first time, but after giving access to the camera it should.
