Title: Unsupervised Learning of Image Correspondences in Medical Image Analysis

Abstract: Image registration is fundamental to many tasks in image analysis. Classical image registration methods have undergone decades of technical development, but are often prohibitively slow since they solve an optimization problem for each 3D image pair. In this talk, I will introduce various models that leverage learning paradigms to enable deformable medical image registration more accurately and substantially faster than traditional methods, crucially enabling new research directions and applications. Based on these models I will discuss a learning framework for building deformable templates, which play a fundamental role in these analyses. This learning approach to template construction can yield a new class of on-demand conditional templates, enabling new analysis. I will also present recent or ongoing models, such as modality-invariant learning-based registration methods that work on unseen test-time contrasts, and hyperparameter-agnostic learning for image registration that removes the need to train different models for different hyperparameters.
