in thread Abstract image registration or feature detection [UPDATED w examples]

Okay, 5.30.2 & PDL 2.021 and 5.32.1 & PDL 2.025 (the last pre-bundled Perl+PDL from Strawberry) both worked like my 5.30.0 & PDL 2.019.

But I was able to install PDL 5.080 with Perl 5.32.1, to get slightly newer PDL but slightly older Perl than you. But it showed the same dimensional difference.

So I did some debug to make it work without PDL::Matrix

This shows the 12-ish pixel error, but will hopefully work with your 2.057 (and definitely worked with my 2.080).
