How to install openCV 2.4.13 for Python 2.7 on Ubuntu 16.04?
According to this source, from Ubuntu 16.04, you can now just do this to install OpenCV for Python2.7:
pip install opencv-python
or for python3:
pip3 install opencv-python
For more information, see here.
I tested this on my machine and it works, great stuff this :).
This is much easier than all other methods I have come across thus far.
There's a script I had made a while back, for installing the latest version of OpenCV (4.2 as of the last update to this answer) Here's the link to it
https://github.com/rsnk96/Ubuntu-Setup-Scripts/blob/master/Build-OpenCV.sh
NOTE: For Ubuntu 16.10+, there are some minor dependency changes you will have to make. Have a look at the comments for the same.
Since you do not want to install opencv contrib, and you specifically want opencv 2.4.13, I have modified the script below. I would suggest you go through the script and understand what is happening before you execute it

sudo make install
echo "finishing off installation"
sudo /bin/bash -c 'echo "/usr/local/lib" > /etc/ld.so.conf.d/opencv.conf'
sudo ldconfig
echo "Congratulations! You have just installed OpenCV. And that's all, folks! :P"
P.S. Create a script file out of this and then just execute the script file, rather than copy-pasting it line by line into the terminal. You can do that by copying all of it, placing it in a file with the extension .sh
, and then simply running that .sh file from the terminal using $ ./filename.sh
sudo apt-get install build-essential cmake git pkg-config sudo apt-get install libjpeg8-dev libtiff4-dev libjasper-dev libpng12-dev sudo apt-get install libgtk2.0-dev sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev sudo apt-get install libatlas-base-dev gfortran sudo apt-get install python2.7-dev sudo pip install numpy sudo apt-get install python-opencv
Then you can have a try:
