FlowSDF: Flow Matching for Medical Image Segmentation Using Distance Transforms

no code implementations28 May 2024 Lea Bogensperger, Dominik Narnhofer, Alexander Falk, Konrad Schindler, Thomas Pock

Medical image segmentation is a crucial task that relies on the ability to accurately identify and isolate regions of interest in medical images.

LoRA-Ensemble: Efficient Uncertainty Modelling for Self-attention Networks

1 code implementation23 May 2024 Michelle Halbheer, Dominik J. Mühlematter, Alexander Becker, Dominik Narnhofer, Helge Aasen, Konrad Schindler, Mehmet Ozgur Turkoglu

We introduce LoRA-Ensemble, a parameter-efficient deep ensemble method for self-attention networks, which is based on Low-Rank Adaptation (LoRA).

MULDE: Multiscale Log-Density Estimation via Denoising Score Matching for Video Anomaly Detection

no code implementations21 Mar 2024 Jakub Micorek, Horst Possegger, Dominik Narnhofer, Horst Bischof, Mateusz Kozinski

We propose a novel approach to video anomaly detection: we treat feature vectors extracted from videos as realizations of a random variable with a fixed distribution and model this distribution with a neural network.

Score-Based Generative Models for Medical Image Segmentation using Signed Distance Functions

no code implementations10 Mar 2023 Lea Bogensperger, Dominik Narnhofer, Filip Ilic, Thomas Pock

Medical image segmentation is a crucial task that relies on the ability to accurately identify and isolate regions of interest in medical images.

Posterior-Variance-Based Error Quantification for Inverse Problems in Imaging

no code implementations23 Dec 2022 Dominik Narnhofer, Andreas Habring, Martin Holler, Thomas Pock

The proposed method employs estimates of the posterior variance together with techniques from conformal prediction in order to obtain coverage guarantees for the error bounds, without making any assumption on the underlying data distribution.
