Overview

This repository hosts implementations of several projects I’ve contributed to, along with helpful preprocessing and post-processing utilities for medical image analysis. It also provides wrappers for selected external packages to enable seamless integration into TransMorph-like registration workflows.

I may include documentation and tutorial scripts depending on interest and available time.
