comment How to detect loops in a vector field?
@Jens: Sure, "contains loops" would have to be interpreted as e.g. "if you follow the vector field, you come back to your point of origin again, up to some numerical error epsilon". But isn't that true of practically any boolean property when you're doing numerical calculations?

comment Smoothen the curve found by EdgeDetect
In v10, I see a thin white border without ImagePadding->None, and EdgeDetect finds another set of edges at the bottom and at the right. Some subtle change due to the new default themes, perhaps.

I had to add ImagePadding -> None to your Plot to get the same result in Mathematica 10.2
