HyperMorph: Amortized Hyperparameter Learning for Image Registration
Overview
Hyperparameter tuning in learning-based registration is a time-consuming process and typically involves training many separate models with various hyperparameter values, potentially leading to suboptimal results. To address this inefficiency, we introduce HyperMorph: amortized hyperparameter learning for image registration, a strategy that learns the effects of hyperparameters on deformation fields, facilitating fast hyperparameter evaluation at test-time.
Visit the tutorial for information on developing and training HyperMorph models or the related demo on interactive hyperparameter tuning. Code can be found in the VoxelMorph and neurite repositories.
