How to Install OpenCV with Modules on Ubuntu Linux

cmake Command:

$ cmake -D WITH_TBB=ON -D INSTALL_C_EXAMPLES=ON -D WITH_EIGEN=OFF -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON -D OPENCV_EXTRA_MODULES_PATH= *path of your contrib_master*/modules ..

Example of the command above if you have your folder at the directory /home/Downloads/:

$ cmake -D WITH_TBB=ON -D INSTALL_C_EXAMPLES=ON -D WITH_EIGEN=OFF -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON -D OPENCV_EXTRA_MODULES_PATH= /home/Downloads/opencv_contrib/modules ..

IMPORTANT: It is recommended to run the following commands before anything:
$ sudo apt-get update
$ sudo apt-get upgrade

NOTE: Please remove the '*' characters when placing the Path to your modules file.

NOTE #1: the double points at the end of the cake command IS NECESSARY! Do not delete!

NOTE #2: The WITH_EIGEN=OFF was used by me because I had an installation problem with the Eigen library. If you prefer, you can try to set it ON

NOTE #3: If you want to see ALL parameters you can install cmake-gui by typing the following command:
$ sudo apt-get install cmake-gui

### FOR THOSE INSTALLING OpenCV 3.2.0 ###

If you are having the error saying something like the following error:

file DOWNLOAD cannot open file for write.
Call Stack (most recent call first):

There is a SOLUTION:
You must download the opencv_contrib-3.2.0 and this is NOT the one on the main github/opencv/opencv_contrib. You must go to the tab RELEASES and see the first release, the 3.2.0. The link is the following:

You will download the version compatible with the OpenCV version you are using it.

Besides this caveat, the steps are the same as described in the video.

Hope it helps!

it has a problem.the path does not include home.to find the path open the terminal in the module folder and copy the adress there, the blue one in terminal.it odes not have home.otherwise it doesnt verify the installation at the end

Also, for those trying to install OpenCV_contrib modules after installing only OpenCV, be sure to make a build folder from scratch! If you try to install it on the same build folder as you previously have, you may get some installing errors!

I downloaded and installed opencv using synaptic manager, and I can't find the build folder, what should I do to compile opencv-contrib ?

[hardnb]

Thank you, how i use the jar in intellij+java, my jar doesn't have any of extra modules inside, is that normal? Or i have to make some reference to opencv_contrib when i add the library in intellij.

Thank you...

I installed OpenCv 3.1 using your video and everything worked like a charm. However, I am working with ros and in order to successfully build a package with the right dependencies, I need to uninstall OpenCV 3.1. Could you please guide me through. I browsed on the internet and it is cardinal to uninstall OpenCV 3.1 in the appropriate way to prevent any broken links.
