VoxelMorph is a Python library for learning-based image registration and alignment, using unsupervised deep learning to model deformations between images. It offers both a PyTorch version under active development and a stable TensorFlow branch, with pre-trained models and tutorials for medical imaging tasks.

Use cases

• register medical images like MRI or CT scans
• align 3D brain volumes with deep learning
• train an unsupervised image registration model
• build anatomical templates with atlas construction
• compute diffeomorphic warps between images
• perform cross-modal registration like CT to MRI

When to choose

• you need fast, learning-based registration of 2D or 3D medical images
• you want unsupervised registration without paired ground-truth deformations
• you need diffeomorphic or probabilistic deformation models
• you want pre-trained models like SynthMorph for brain MRI alignment

When to avoid

• you need simple rigid or affine registration of a few images without training
• you require a fully stable API and prefer not to track active development
• your project does not involve deep learning or GPU compute
• you need registration for non-volumetric data like plain documents
