Towards Positive Jacobian: Learn to Postprocess Diffeomorphic Image Registration with Matrix Exponential
Soumyadeep Pal, Matthew Tennant, Nilanjan Ray
We present a postprocessing layer for deformable image registration to make a registration field more diffeomorphic by encouraging Jacobians of the transformation to be positive. D…
Ordinary Differential Equation and Complex Matrix Exponential for Multi-resolution Image Registration
Abhishek Nan, Matthew Tennant, Uriel Rubin +1
Autograd-based software packages have recently renewed interest in image registration using homography and other geometric models by gradient descent and optimization, e.g., AirLab…
DRMIME: Differentiable Mutual Information and Matrix Exponential for Multi-Resolution Image Registration
Abhishek Nan, Matthew Tennant, Uriel Rubin +1
In this work, we present a novel unsupervised image registration algorithm. It is differentiable end-to-end and can be used for both multi-modal and mono-modal registration. This i…
