Unsupervised dynamic modeling of medical image transformation

2 code implementations1 Mar 2021 Niklas Gunnarsson, Peter Kimstrand, Jens Sjölund, Thomas B. Schön

For this, we use a conditional variational auto-encoder (CVAE) to nonlinearly map the higher-dimensional image to a lower-dimensional space, wherein we model the dynamics with a linear Gaussian state-space model (LG-SSM).

Together with a sparse-to-dense interpolation scheme we can then estimate of the displacement field.
