Hi, This small application which adjusts the brightness of the screen based on the ambient light in the room. It uses the inbuilt camera in your laptop and opencv libraries to do image processing. I just finished making the prototype of this project today and it is working nicely. There are loads of things still left to do and the tedious of them all is to make a debian package for it :) Anybody interested in contributing to this project can check out the following links The wiki page : http://gitorious.org/luminos/pages/Home Contains all the information about the project including the basic algorithm and links to the git repository.
