Open Computer Vision (OpenCV) :
OpenCV is an open source computer vision library.
For download (See http://sourceforge.net/projects/opencvlibrary/ ).
This can be written in C, C++ and runs under Lunix, Windows and MacOs X.
Active development of this is done on interfaces for Python,Ruby,Matlab and other languages.
This is mostly used by computer scientists and Programmers for real time applications.
To know more about computer vision and for refereces you can visit http://opencv.willowgarage.com/wiki/.
There are many ways to deal with programming of OpenCV. It took me lot of time to make things together as they were messed up everywhere and some were out dated.
So lets deal with easy installation and its applications from the next post.
