[ITK-users] Segfault in Wiki Example: QuadEdgeMeshParameterizationFilter

[Arnaud Gelas]

Could you make pull requests to fix this code, please?

Not sure who can accept pull request for midas-journal account though :-/…
If that’s not easily doable, we could import these contributions in the InsightSoftwareConsortium’s organization.

Best
Arnaud
