Is possible to get High Quality video from Low Quality ?

You can improve the quality a bit with interpolation. Like the Open Source VLC Player does. But normally you cant win much with it.

The common way would be to apply some image effects like in the outstanding CXImage project for EVERY frame.

All not very well, so the best way is to get high quality source videos. ;-)

A definitive NO.
There is no general purpose process permitting to double the resolution of a picture or a video.
Interpolation is only a tool to improve smoothness after a picture resize, and it is only probabilistic.

By the way, only on TV series, they use screen display in the process of matching finger prints or face recognition. In reality, screen display is slowing the process.

I know only one think that approach what you want:
By taking a video sequence, you can improve the quality of 1 moving detail by combining the picture from the video. And it don't work on anything, and result is not insured.
