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

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.

Image Segmentation Segmentation +2

Projection-Based 2.5D U-net Architecture for Fast Volumetric Segmentation

no code implementations1 Feb 2019 Christoph Angermann, Markus Haltmeier, Ruth Steiger, Sergiy Pereverzyev Jr, Elke Gizewski

While for 2D images these networks are also computationally efficient, 3D convolutions have huge storage requirements and require long training time.
