Here's a video sample of The Dark Knight Blu Ray matched to Screener colors.

I've used mostly just one rotation, as it went faster this way. There are however, small shots at the beginning that use all rotation matrices, which results in a better matching.

Here are the three images compared:

I'm going to play with the rotaion matrices a little bit. Maybe I will calculate even less than 20, because the matching is really slow, if all 20 rotations are used. There is also sometimes heavy noise, if more than one rotation is used.
