Does OpenCV work with C++?

OpenCV is an open source C++ library for image processing and computer vision, originally developed by Intel, later supported by Willow Garage and and is now maintained by Itseez. It is free for both commercial and non-commercial use. Therefore you can use the OpenCV library even for your commercial applications.

Can I use OpenCV in Visual Studio?

Open your Visual Studio Installer tool and add C++ for desktop development as a workload to your current Visual Studio IDE version. This step is essential since you can not use OpenCV in VS without all the C++ required libraries.

4. Step 4: Check out demo code!

Is C++ good for OpenCV?

It is normally used for combining best features of both the languages, Performance of C/C++ & Simplicity of Python. So when you call a function in OpenCV from Python, what actually run is underlying C/C++ source. So there won’t be much difference in performance.
