Current Projects

VoxelMorph: Unsupervised Learning for Image Registration

VoxelMorph is a fast, unsupervised, learning-based framework for deformable, pairwise medical image registration. VoxelMorph combines a probabilistic model with unsupervised learning that makes use of recent developments in convolutional neural networks (CNNs). This results in state of the art accuracy and very fast runtimes, while providing diffeomorphic guarantees and uncertainty estimates.

Anatomical Priors in Convolutional Networks for Biomedical Segmentation

In this project we specifically address the frequent scenario where we have no (or very few) paired training data that contains images and their manual segmentations. We explore generative probabilistic models that employ priors learned from external data through convolutional neural networks, enabling segmentations in unsupervised or semi-supervised settings.

Unsupervised Data Imputation

In this project we focus on unsupervised estimation of missing image data, where no full observations are available - a common situation in practice. Unsupervised imputation methods for images often employ a simple linear subspace to capture correlations between data dimensions, ignoring more complex relationships. Instead, we work with a general probabilistic model that describes sparse high dimensional imaging data as being generated by a deep non-linear embedding.
