Summary

Poisson Flow turns branching geometry into smooth distributions before comparing shapes.

A registration method transforms tree structures into multiscale smooth distributions and optimizes a Wasserstein objective without explicit landmarks or branch correspondence. The authors demonstrate the approach on cortical folding extracted from MRI; the preprint does not establish clinical diagnostic utility.
