Installing OpenCV 2.4.13 on Ubuntu 16.04

Sun, Oct 16, 2016Tags: #OpenCV #Ubuntu #C++ #CMake

This post is (for the most part) note to self. Please follow with caution.

Optional Pre-Clean Up

If created with make install then make uninstall
Else if created with checkinstall then dpkg -r release
Else sudo apt-get purge libopencv* && sudo apt-get autoremove

Additional files to remove:
sudo rm -rf /usr/local/include/opencv/
sudo rm -rf /usr/local/include/opencv2/
sudo rm -rf /usr/local/share/OpenCV/
sudo find /var/cache/apt/archives/ -name \*opencv\* -exec rm -rf {} \;
sudo find /usr/local/lib/ -name \*opencv\* -exec rm -rf {} \;
sudo find /usr/local/bin/ -name \*opencv\* -exec rm -rf {} \;

Run Sample OpenCV program

Save code below as DisplayImage.cpp

#include <stdio.h>
#include <opencv2/opencv.hpp>

using namespace cv;

int main(int argc, char** argv )
{
    if ( argc != 2 )
    {
        printf("usage: DisplayImage.out <Image_Path>\n");
        return -1;
    }

    Mat image;
    image = imread( argv[1], 1 );

    if ( !image.data )
    {
        printf("No image data \n");
        return -1;
    }
    namedWindow("Display Image", WINDOW_AUTOSIZE );
    imshow("Display Image", image);

    waitKey(0);

    return 0;
}



~$ sudo g++ DisplayImage.cpp -o DisplayImage `pkg-config --cflags --libs opencv`
~$ ./DisplayImage [path-to-image]

---

Compile using CMake

Create CMakeLists.txt on the same level as the main source file with the following code:

cmake_minimum_required( VERSION 2.8 )
project( DisplayImage )
set( OpenCV_DIR "/usr/share/OpenCV/" )
find_package( OpenCV REQUIRED )
add_executable( DisplayImage DisplayImage.cpp )
target_link_libraries( DisplayImage ${OpenCV_LIBS} )

Create a build folder on the same level as the other two files. You can name it however you want. cd into the folder and cmake .. then make.

~$ mkdir build && cd build
~/build$ cmake ..
-- The C compiler identification is GNU 5.4.0

~/build$ make

Overall project structure looks like below:

~$ tree -L 2
.
├── build
│   ├── CMakeCache.txt
│   ├── CMakeFiles
│   ├── cmake_install.cmake

    }
    namedWindow("Display Image", WINDOW_AUTOSIZE );
    imshow("Display Image", image);

    waitKey(0);

    return 0;
}

Build and Run.
