SSTFB: Leveraging self-supervised pretext learning and temporal self-attention with feature branching for real-time video polyp segmentation

Ziang Xu, Jens Rittscher, Sharib Ali

Polyps are early cancer indicators, so assessing occurrences of polyps and their removal is critical. They are observed through a colonoscopy screening procedure that generates a s…

SSL-CPCD: Self-supervised learning with composite pretext-class discrimination for improved generalisability in endoscopic image analysis

Ziang Xu, Jens Rittscher, Sharib Ali

Data-driven methods have shown tremendous progress in medical image analysis. In this context, deep learning-based supervised methods are widely popular. However, they require a la…

Patch-level instance-group discrimination with pretext-invariant learning for colitis scoring

Ziang Xu, Sharib Ali, Soumya Gupta +3

Inflammatory bowel disease (IBD), in particular ulcerative colitis (UC), is graded by endoscopists and this assessment is the basis for risk stratification and therapy monitoring.…

Assessing generalisability of deep learning-based polyp detection and segmentation methods through a computer vision challenge

Sharib Ali, Noha Ghatwary, Debesh Jha +29

Polyps are well-known cancer precursors identified by colonoscopy. However, variability in their size, location, and surface largely affect identification, localisation, and charac…

A Graph Based Neural Network Approach to Immune Profiling of Multiplexed Tissue Samples

Natalia Garcia Martin, Stefano Malacrino, Marta Wojciechowska +8

Multiplexed immunofluorescence provides an unprecedented opportunity for studying specific cell-to-cell and cell microenvironment interactions. We employ graph neural networks to c…

A multi-centre polyp detection and segmentation dataset for generalisability assessment

Sharib Ali, Debesh Jha, Noha Ghatwary +12

Polyps in the colon are widely known cancer precursors identified by colonoscopy. Whilst most polyps are benign, the polyp's number, size and surface structure are linked to the ri…
