Image Manipulation
==================
.. todo::
Add introduction about image manipulation and its Python libraries.
Most image processing and manipulation techniques can be carried out effectively using
two libraries: Python Imaging Library (PIL) and OpenSource Computer Vision (OpenCV).

A brief description of both is given below.

OpenSource Computer Vision, more commonly known as OpenCV, is a more advanced image manipulation and processing software than PIL. It has been implemented in several

Installation
~~~~~~~~~~~~
In Python, image processing using OpenCV is implemented using the ``cv2`` and ``NumPy`` modules.
The `installation instructions for OpenCV <http://docs.opencv.org/2.4/doc/tutorials/introduction/table_of_content_introduction/table_of_content_introduction.html#table-of-content-introduction>`_ should guide you through configuring the project for yourself.

NumPy can be downloaded from the Python Package Index(PyPI):
.. code-block:: console
$ pip install numpy
