This sounds like it's well worth figuring out. The new results, apart from the regions shown, are excellent. I wonder if @TAdeJong, who is intimately familiar with the issue, would...

`CACHEDIR.TAG` is fine to add; just had to :roll_eyes: at: > This signature header is required to avoid the chance of an unrelated file named CACHEDIR.TAG being mistakenly interpreted as...

Key to a good circularity estimate is using an accurate perimeter estimation. See @crisluengo's comment on Steve's blog post.

Let's hear what @haesleinhuepf thinks of https://github.com/scikit-image/scikit-image/pull/6713#issuecomment-1740547670 and https://github.com/scikit-image/scikit-image/pull/6713#issuecomment-1740815450. In principle, we're on board with getting circularity in.

@lagru Want to update this to have the improved definition, then we can move ahead?

It's a bit of a pain either way; but it's probably easier to follow the scipy route than modifying the plausible ping.

I ran into this same issue recently, and may have fixed it in a few places. I looked at behavior a few versions back, but it looked this angle definition...

I'm leaving some comments [here](https://github.com/scikit-image/scikit-image/pull/7031#issuecomment-1863238694). Something weird is up with rotation. **EDIT:** :sweat_smile: Phew, took me a while! https://github.com/scikit-image/scikit-image/pull/7031#issuecomment-1863431779

The problem with setting the seed in gallery examples is that this is not what we'd like the user to do in practice. The gallery is meant to show code...
