Are there paper about black box testing of optic flow algorithms? Do papers exist about comparisons of the resulting optic flow and its precision compared to the used optic flow method?

I would like to find paper that dealt with this topic in some way and had discussed different ways to conquer this problem.

Thank you in advance.
There is Middlebury, which evaluates almost all the algorithms and their evaluation results are online:

Or simply click any of the links at: http://vision.middlebury.edu/flow/eval/

They also have a paper on their research and evaluation methodology.
