Masked Image Modelling for retinal OCT understanding

no code implementations23 May 2024 Theodoros Pissas, Pablo Márquez-Neila, Sebastian Wolf, Martin Zinkernagel, Raphael Sznitman

To this end, we leverage Masked Autoencoders (MAE), a simple and scalable method for self-supervised learning, to obtain a powerful and general representation for OCT images by training on 700K OCT images from 41K patients collected under real world clinical settings.

Stochastic Segmentation with Conditional Categorical Diffusion Models

1 code implementation ICCV 2023 Lukas Zbinden, Lars Doorenbos, Theodoros Pissas, Adrian Thomas Huber, Raphael Sznitman, Pablo Márquez-Neila

Semantic segmentation has made significant progress in recent years thanks to deep neural networks, but the common objective of generating a single segmentation output that accurately matches the image's content may not be suitable for safety-critical domains such as medical diagnostics and autonomous driving.

Multi-scale and Cross-scale Contrastive Learning for Semantic Segmentation

1 code implementation25 Mar 2022 Theodoros Pissas, Claudio S. Ravasio, Lyndon Da Cruz, Christos Bergeles

We apply contrastive learning to enhance the discriminative power of the multi-scale features extracted by semantic segmentation networks.
