Upper bound for realtime application I have developped an application for image inpainting. Now I want to claim that it can be used for realtime purposes.

Does somebody know a paper which gives some boundaries for realtime applications? I want to refer to a paper to prove my assumption.
Real time means that your algorithm can process the video faster than the time it takes to watch the video. In other words, if you were collecting the video live you would be able to finish processing it as soon as you stopped collecting it with no extra work needed to be done after.
