This enables flexible task-specific registration without ad-hoc hyperparameter tuning. So far we've looked at brain MRI registration using cLapIRN and NiftyReg, but we're looking to extend to more modalities and different scenarios so get in touch if you want to collaborate.

In this work we demonstrate how to use ML for predicting the (often substantial) effect of regularisation hyperparameters when registering image pairs. Our approach allows us to efficiently infer the instance-specific optimal hyperparameter at test time without labelled data.
