The role of noise in denoising models for anomaly detection in medical images

1 code implementation19 Jan 2023 Antanas Kascenas, Pedro Sanchez, Patrick Schrempf, Chaoyang Wang, William Clackett, Shadia S. Mikhael, Jeremy P. Voisey, Keith Goatman, Alexander Weir, Nicolas Pugeault, Sotirios A. Tsaftaris, Alison Q. O'Neil

Denoising methods, for instance classical denoising autoencoders (DAEs) and more recently emerging diffusion models, are a promising approach, however naive application of pixelwise noise leads to poor anomaly detection performance.

Pseudo-label refinement using superpixels for semi-supervised brain tumour segmentation

no code implementations16 Oct 2021 Bethany H. Thompson, Gaetano Di Caterina, Jeremy P. Voisey

Our framework combines superpixels with semi-supervised learning, refining the pseudo-labels during training using the features and edges of the superpixel maps.
