Sparse2Inverse: Self-supervised inversion of sparse-view CT data

no code implementations26 Feb 2024 Nadja Gruber, Johannes Schwab, Elke Gizewski, Markus Haltmeier

Sparse-view computed tomography (CT) enables fast and low-dose CT imaging, an essential feature for patient-save medical imaging and rapid non-destructive testing.

Computed Tomography (CT) Image Reconstruction

Single-Image based unsupervised joint segmentation and denoising

no code implementations19 Sep 2023 Nadja Gruber, Johannes Schwab, Noémie Debroux, Nicolas Papadakis, Markus Haltmeier

To this end, we combine the advantages of a variational segmentation method with the power of a self-supervised, single-image based deep learning approach.

Image Denoising Segmentation

Variational multichannel multiclass segmentation using unsupervised lifting with CNNs

no code implementations4 Feb 2023 Nadja Gruber, Johannes Schwab, Sebastien Court, Elke Gizewski, Markus Haltmeier

We propose an unsupervised image segmentation approach, that combines a variational energy functional and deep convolutional neural networks.
