Right Regions, Wrong Labels: Semantic Label Flips in Segmentation under Correlation Shift

Akshit Achara, Yovin Yahathugoda, Nick Byrne +4

The robustness of machine learning models can be compromised by spurious correlations between non-causal features in the input data and target labels. A common way to test for such…

A persistent homology-based topological loss for CNN-based multi-class segmentation of CMR

Nick Byrne, James R Clough, Isra Valverde +2

Multi-class segmentation of cardiac magnetic resonance (CMR) images seeks a separation of data into anatomical components with known structure and configuration. The most popular C…

A persistent homology-based topological loss function for multi-class CNN segmentation of cardiac MRI

Nick Byrne, James R. Clough, Giovanni Montana +1

With respect to spatial overlap, CNN-based segmentation of short axis cardiovascular magnetic resonance (CMR) images has achieved a level of performance consistent with inter obser…

A Topological Loss Function for Deep-Learning based Image Segmentation using Persistent Homology

James R. Clough, Nicholas Byrne, Ilkay Oksuz +3

We introduce a method for training neural networks to perform image or volume segmentation in which prior knowledge about the topology of the segmented object can be explicitly pro…

Topology-preserving augmentation for CNN-based segmentation of congenital heart defects from 3D paediatric CMR

Nick Byrne, James R. Clough, Isra Valverde +2

Patient-specific 3D printing of congenital heart anatomy demands an accurate segmentation of the thin tissue interfaces which characterise these diagnoses. Even when a label set ha…

Explicit topological priors for deep-learning based image segmentation using persistent homology

James R. Clough, Ilkay Oksuz, Nicholas Byrne +2

We present a novel method to explicitly incorporate topological prior knowledge into deep learning based segmentation, which is, to our knowledge, the first work to do so. Our meth…
