Bad performance in two identical images ! #29

@philferriere Hi, when I test the pre-train model with image pairs that they are the same or samll motion, results of optical flow prediction are not good. Is this case not taken into account when training?

@HuangLian126 I also meet this problem, do you solve it?

It's been my observation as well. And I have seen it happen with PWC and FlowNet. I don't think it's an implementational error, it's more of a weak point of the algorithm itself i guess..
