Thanks for showing this, following your cheatsheet makes my life way easier than all other tutorials I found elsewhere.

I just wanna say, you are the best for making these videos, if I wasn't so broke I would donate. Maybe I'll skip a few meals and send some $ your way.

Dear Chris,
Just to collaborate with such a wonderful effort teaching so many of us, on QT Creator 3.6.1, after pressing Next on item 5d, there's a new session called Build System, with options for qmake/Cmake/Qbs. Thought you might want to update it.
I'll make sure to contribute with this great work through Patreon. Thanks a lot!
Greetings from Brazil.

Thank you a thousand times for this tutorial! You helped me so much :)

Thank-you for this excellent video. Great work!

[davidchen]

This is an amazing tutorial. Thank you so much!

Great tutorial! One nitpicky comment, using the replace all function in notepad to remove the file extention and quotations is much faster than manually deleting them

Chris, again great videos man! I've followed this Opencv 3 install with QT and it worked great! Would you be able to help me integrate a machine vision camera into the last app? I've got a Point Grey camera(s) that I got working with your non GUI QT project (QT console, opencv and point grey camera), but I'm getting stuck trying to use the cameras with the GUI QT example. Anyways, keep up these awesome videos!

Great videos! What about a standalone headless computer vision system using something like the Beaglebone Black or the Raspberry Pi 2 running Linux and a Webcam? The project could be used to turn the on/off hardware based on what the camera is assigned to do? Thank you.

hi chris, i have tried the CannyStill.cpp with non_gui on qt, but i have to make the absolute pathname to the imread() function, in my case its "E:\\W_workspaceQT\\CannyStill_X\\image.jpg", however, in your program, i noticed that the name you put its just "image.jpe", i have already copied the picture into the project directory, i.e. CannyStill_X. so how to set to the relative path for imread().

HEY.. great video, but i have a question, can i follows this steps with the opencvCONTRIB? because i need other modules like aruco markers ..

[RoBuceo]

Hi, thank you very much for the tutorial. Its great!
Im having an error message after i tried to run the "CannyStill" Win32 Consle Application.
The message says :"This application failed to start because it could not find or load the Qt platform plugin "windows"

Sir Can you cover Vehicle counter in the road using OpenCV? Like counting different kinds of vehicles (bus, Van, Cars). I would like so see how it is done using OpenCV

[jacobjohnston]

I got an error installing CMake: "Warning PATH too long installer unable to modify PATH" and I don't see any applicalbe path when checking in cmd... is there a good workaround? Not sure which path to add manually, of so.

[heiditroppen]

Hi! Do you know how to build openCV using CMake without internet?

[danielbabatunde]

Hey, I'm following this tutorial and core.hpp, highgui.hpp and imgproc.hpp cannot be found. there is nothing in opencv-3.0.0/build but there is a opencv2.hpp file in my folder. Any help?

[leventekovacs]

Dear Chris,
I followed your steps correctly, and I can compile without any issues, but when I run the program, its immediately crash without any error, what do you suggest? ( opencv 3.0, Qt 5.5 32 bit, win 10)

i'd like to ask you about GPU modules and opencv, is it possible to use this module without a nvidia card, and if yes, could make us a video on that pleaze
