Hi Mahesh,

While your patch does basically work, I'm not entirely sure what you are 
trying to accomplish.

You added the functionally straight to the main context ui and therefore 
basically hardcoded the dependency to opencv. In an earlier mail I suggested 
to put this into a context plugin - in part to avoid the hard dependency. You 
never answered that mail or even explained why you seem to think that 
hardcoding it is the way to go when submitting the patch.

If you are trying to show me that you can find your way around a (rather) large 
codebase: Yes you found the context ui on your own which kind off earns you 
some bonus points.
But if you'd have asked I'd have told you that I think that's the wrong place 
to put it. Also, you seem to have copy & pasted the opencv detection code for 
cmake from libkface and failed to give proper attribution.

So I guess that it's just a functional "mockup" - a way of showing off the face 
detection.

But then again: Why such a simple example? Even the wiki article on face 
detection with opencv on willowgarage (the first hit when googling "opencv face 
detection") has a finished example with live webcam input.

So yes, it works. But what exactly am I looking at?

Best regards,
Peter
