ENH: Bump elastix to 5.3.0

[N-Dekker]

Follow-up to pull request #344 commit 2821abb
"COMP: Use upstream elastix repository", July 2025.

@N-Dekker it looks like we get a slight difference in the registration, resulting in a small out-of-domain sampling at the lower left:

perhaps we increase the baseline comparison tolerance to allow more pixels? Or add a new baseline?

Thanks Matt. I see, you did already increase the tolerance before. Two times already:

• Feb 15, 2021: a75a5b0
• Apr 21, 2024: f202da6

So then, I wonder, what would cause these new differences? I wonder, would they be introduced by SuperElastix/elastix, somewhere between those revisions? SuperElastix/elastix@8c4f347...798346c

Is the registration result still fine anyway?

Update: Maybe it's pull request SuperElastix/elastix#1361 commit SuperElastix/elastix@6f031a5 (Reduce rounding errors "GridSpacingSchedule" GetDefaultParameterMap) So then indeed, we should have a new baseline! Can someone please 🙏 help me to get it there?

[N-Dekker]

Update: this commit BUG: Replace default values of "GridSpacingSchedule" in test aims to solve the test failure without changing the baseline 🙏

Looks good on a glance.

@N-Dekker great work!!

Looks like it will be green with a formatting fix.

[N-Dekker]

Thanks for your encouranging comments @dzenanz, @thewtex I just moved the commit BUG: Replace default values of "GridSpacingSchedule" in test to its own pull request (#365), as I think it can already be applied before upgrading SuperElastix/elastix.

Build / py-dev / build-linux-py (11, 2014-x64) (pull_request) fails, saying:

Searching for wheels matching pattern dist/itk_*cp311*manylinux2014*x86_64.whl

I'll give it another try!

When this is merged, shall we also make a new tag for ITKElastix? What about v0.24.0?

@N-Dekker 🎇

Yes, we need to make sure to update the version first, here:

ITKElastix/pyproject.toml

Line 7 in f43d560

version = "0.23.0"
