Install opencv without root permission

1. Download old versions of OpenCV

- If gcc on my system is outdated, I may need to install an old-version of opencv.

- Visit at http://sourceforge.net/projects/opencvlibrary/files/

- In my system (Fedora release 10 (Cambridge)), the OpenCV-2.4.1 or before seems to work.

2. Installation ([2][3])

- Run the following.

>> tar -xvf  OpenCV-2.4.0.tar.bz2

>> cd  ~/OpenCV-2.4.0/

>> mkdir release

>> cd release

>> cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/home/gunhee/lib/opencv2.4 -D BUILD_PYTHON_SUPPORT=ON -D PYTHON_EXECUTABLE=/home/gunhee/lib/python-2.7.3/bin/python -D PYTHONINTERP_FOUND=1 ..

(Assume that the python interpreter is at 'PYTHON_EXECUTABLE=/home/gunhee/lib/python-2.7.3/bin/python'.)

>> make

>> make install

- Add the following to the .bashrc file [3].

# opencv
export LD_LIBRARY_PATH=/home/gunhee/opencvlib/lib:$LD_LIBRARY_PATH
export PKG_CONFIG_PATH=/home/gunhee/opencvlib/lib/pkgconfig/:$PKG_CONFIG_PATH

- Test as follows to make sure whether the installation is successful [2].

>> cd ~/OpenCV-2.4.1/samples/c

>> sh  build_all.sh

>> ./facedetect  lena.jpg

- Test as follows to make sure whether the installation (for python) is successful [1].

>> cp ~/OpenCV-2.4.1/release/lib/cv2.so ~/lib/python-2.7.3/lib/python2.7/site-packages/

>> cd ~/OpenCV-2.4.1/samples/python

>> python delaunay.py
