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

1 code implementation27 Jul 2021 Nick Byrne, James R Clough, Isra Valverde, Giovanni Montana, Andrew P King

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

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

no code implementations21 Aug 2020 Nick Byrne, James R. Clough, Giovanni Montana, Andrew P. King

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 observer variation.

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

no code implementations23 Aug 2019 Nick Byrne, James R. Clough, Isra Valverde, Giovanni Montana, Andrew P. King

In a series of five-fold cross-validations, we demonstrate the performance gain produced by this pipeline and the relevance of topological considerations to the segmentation of congenital heart defects.
