Towards Positive Jacobian: Learn to Postprocess Diffeomorphic Image Registration with Matrix Exponential
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.
Ordinary Differential Equation and Complex Matrix Exponential for Multi-resolution Image Registration
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 and DRMIME.
DRMIME: Differentiable Mutual Information and Matrix Exponential for Multi-Resolution Image Registration
In this work, we present a novel unsupervised image registration algorithm.
