Installing OpenCV in Ubuntu14.04(trusty)/13.10(saucy)

First, download the latest version of Open-CV from here :

Now install the dependencies:


 sudo apt-get install build-essential 


 sudo apt-get install cmake 

Use Synaptic Package Manager to install these packages:
Python,Python-dev, Numpy, libavcodec-dev, libavformat-dev, libswscale-dev

Optional packages: libjpeg-dev, libpng-dev, libtiff-dev, libjasper-dev,lib1394 2.x

Now extract the opencv zip file and go to the extracted directory.

Next create a build directory and go into that:

 mkdir build
 cd build 

Next execute :

 cmake ../ 
 sudo make
 sudo make install 

If everything is done correctly Open-CV is installed and ready to work with.
