[edit] Description of FR metrics is incorrect
FR metrics do not necessarily perform a pixelwise comparison of the images. Instead, some metrics may perform filtering of the images before comparing them. Also, they may compare only subregions or downscaled (=averaged)regions of the images. It also happens, that some metrics extract one value(e.g. jerkiness) from the reference video, extract the same value from the degraded video and then compare these two somehow averaged values. In this case no imagewise comparison would happen at all. I am still thinking about a good text to correct this. If somebody has a good idea how to phrase it, go ahead...

[edit] Further Reading
Only a minor thing. Shouldn't the link to ITU say ITU-R instead of ITU-T?
