The build directory will be used for saving the result of building process, and the source folder will contain all of the OpenCV and its extra modules sources.
We can download OpenCV sources together with the extra modules from this following websites:. After finish downloading, unzip each of them to designated folders as depicted in figure below:. The red box must be filled with the directory path of OpenCV source, and the green box must be filled with the directory path of designated build folder.
Since I use Visual Studio in bit machine, I will use the following configuration. If everything goes well, the tracking module should also be there. Here is the example result of re-configuring the CMake with extra modules.
Note : if you use the C: directory probably you will need an Administrator privilege to build the OpenCV project, so you must also run the Visual Studio under the Administrator privilege. It may take several minutes for the whole building process to finish, just be patient. Whenever the whole building process has been done, there will be several resulting new directories, such as: install, bin, and lib directory inside the build directory.
Here is how it looks like inside the install directory whenever the whole building process has been finished. Now, we have already finished building our own OpenCV library as well as its extra modules.
Now, that we have already built the OpenCV library, we can use it to build our own application which uses OpenCV great features. There are two main steps that are required:. Before we are able to use OpenCV in our application, we need to register OpenCV path to our system environment variables.
Here is the example:.
By doing this, it will be easy for you to maintain your Open CV library. Just update this environment variable once you have the latest Open CV version. This will help when updating our Open CV version in the future.
Here are the steps:.

Could you clarify what are all the directories to be included when modifying the properties of the VS project? I am glad, that this tutorial has saved people from having bad times in building and installing OpenCV. Thank you very much for this tutorial. It really helped me a lot and I was able to program some command line programs.
Now I want to have a GUI but this seems a bit tricky. Could you also explain how to build OpenCV so that using the Qt features is possible? I am not sure whether I can make that tutorial in the near future since I am having a tight schedule nowadays.
However, someone else has just made a tutorial that may help you. Please check his post. Thats what I did it in the end. I was just wondering how to make such things in VSOpenCV has 35 modules, is there a documenting elaborating the dependencies for each of them?
Thanks a lot. I will select only a new modules and include all the dependencies 3rd party headers and libs for these modules in one package. So no matter in which machine I use OpenCV, it's always self-inclusive, no need to install these dependencies for each machine. From all the tutorials about installation, they installed many other all different kinds of libraries not from t OpenCV self included 3rd party.
I think this is only the dependency inside OpenCV module. I am looking for dependencies inside and outside of OpenCV module. Thanks LBerger. I am looking at OpenCV 3. Asked: Conversion between IplImage and MxArray. Problems installing opencv on mac with python. Problems using the math. How to reduce false positives for face detection. First time here?

Those instructions are really old, I would follow a more up to date guide like Accelerating OpenCV 4. That guide also has instructions for accelerating the build with ninja and including bindings for accessing the opencv cuda modules from within python.
And i got it build a week ago from the script i mentioned, but this error, i am getting it recently since last 2 days. Thanks for the link.
Il follow steps over there and try to build it but i am actually interested in why i am getting this error. Are you building from the master or from a specific release 3. If you are building from the master then it could be anything as changes are pushed all the time and you are best asking on git hub. It is simple to do, once you know it is needed but there are a lot of rabbit trails and mis-information out there if you google the error message. Asked: Can't compile.

If nothing happens, download GitHub Desktop and try again. If nothing happens, download Xcode and try again. If nothing happens, download the GitHub extension for Visual Studio and try again. This repository is intended for development of so-called "extra" modules, contributed functionality. New modules quite often do not have stable API, and they are not well-tested.
Thus, they shouldn't be released as a part of official OpenCV distribution, since the library maintains binary compatibility, and tries to provide decent performance and stability. Later, when the module matures and gains popularity, it is moved to the central OpenCV repository, and the development team provides production quality support for this module. You can build OpenCV, so it will include the modules from this repository.
Contrib modules are under constant development and it is recommended to use them alongside the master branch or latest releases of OpenCV.
Like in this example:. Here you add your model with a single line description. This README explains which functionality separate functions is available, links to the corresponding samples and explains in somewhat more detail what the module is expected to do. If any extra requirements are needed to build the module without problems, add them here also. Skip to content.
