image quality of compressed video

[chacademus]

Does anybody know whether there is a way of measuring the quality of compressed video? I ask, as part of my academic studies has partly to do with this. I'm not sure whether there is a tool of this kind or whether you can or cannot measure something like this. Any information would be greatly appreciated.:D

I don't remember the link but I saw a web site recently on doing reverse filtering and they were measuring the success by the mean squared error from the original. But it was a little depressing because that did not really seem to correspond very well to the visual quality that I would look for.

I had been considering tuning a deinterlace method using genetic algorithms and measuring like this, so it was a small setback. But I still don't know a better way.
