Navigating Uncertainty in Medical Image Segmentation

no code implementations23 Jul 2024 Kilian Zepf, Jes Frellsen, Aasa Feragen

We address the selection and evaluation of uncertain segmentation methods in medical imaging and present two case studies: prostate segmentation, illustrating that for minimal annotator variation simple deterministic models can suffice, and lung lesion segmentation, highlighting the limitations of the Generalized Energy Distance (GED) in model selection.

That Label's Got Style: Handling Label Style Bias for Uncertain Image Segmentation

no code implementations28 Mar 2023 Kilian Zepf, Eike Petersen, Jes Frellsen, Aasa Feragen

Segmentation uncertainty models predict a distribution over plausible segmentations for a given input, which they learn from the annotator variation in the training set.

Laplacian Segmentation Networks Improve Epistemic Uncertainty Quantification

1 code implementation23 Mar 2023 Kilian Zepf, Selma Wanna, Marco Miani, Juston Moore, Jes Frellsen, Søren Hauberg, Frederik Warburg, Aasa Feragen

Image segmentation relies heavily on neural networks which are known to be overconfident, especially when making predictions on out-of-distribution (OOD) images.
