Compiling and installing OpenCV

To compile and install OpenCV, we need to go through the following steps:

1. Go inside the opencv-4.0.0 folder. Change the directory to the opencv-4.0.0 folder using the following command:

cd opencv-4.0.0

2. Inside this folder, create a build folder. To do so, type the following command:

mkdir build

3. To open the build directory, type the following command:

cd build

4. After changing the directory to build, enter the following command:

cmake -D CMAKE_BUILD_TYPE=RELEASE \-D CMAKE_INSTALL_PREFIX=/usr/local \-D BUILD_opencv_java=OFF \-D BUILD_opencv_python2=OFF \-D BUILD_opencv_python3=ON \-D PYTHON_DEFAULT_EXECUTABLE=$(which python3) \-D INSTALL_C_EXAMPLES=ON \-D INSTALL_PYTHON_EXAMPLES=ON \-D BUILD_EXAMPLES=ON\ ...
