 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).

 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.
