Compressed Sensing MRI Reconstruction Regularized by VAEs with Structured Image Covariance

no code implementations26 Oct 2022 Margaret Duff, Ivor J. A. Simpson, Matthias J. Ehrhardt, Neill D. F. Campbell

The covariance can model changing uncertainty dependencies caused by structure in the image, such as edges or objects, and provides a new distance metric from the manifold of learned images.

no code implementations22 Jul 2021 Margaret Duff, Neill D. F. Campbell, Matthias J. Ehrhardt

The success of generative regularisers depends on the quality of the generative model and so we propose a set of desired criteria to assess generative models and guide future research.
