Endoscopy Disease Detection and Segmentation (EDD2020)

Endoscopy is a widely used clinical procedure for the early detection of cancers in hollow-organs such as oesophagus, stomach, and colon. Computer-assisted methods for accurate and temporally consistent localisation and segmentation of diseased region-of-interests enable precise quantification and mapping of lesions from clinical endoscopy videos which is critical for monitoring and surgical planning. Innovations have the potential to improve current medical practices and refine healthcare systems worldwide. However, well-annotated, representative publically-available datasets for disease detection for assessing reproducibility and facilitating standardised comparison of methods is still lacking. Many methods to detect diseased regions in endoscopy have been proposed however these have primarily focussed on the task of polyp detection in the gastrointestinal tract with demonstration on datasets acquired from at most a few data centres and single modality imaging, most commonly white light. Here, we present our multi-class disease detection and segmentation challenge in clinical endoscopy. With this sub-challenge we aim to establish a comprehensive dataset to benchmark algorithms for disease detection. Specifically we aim to assess: Precise spatio-temporal localisation of disease regions using bounding boxes and exact pixel-level segmentation. Clinical applicability by assessing the online sequential for real-time monitoring and offline performance of algorithms for improved accuracy and better quantitative reporting. Participants will be provided with a set of annotated dataset labelled by medical experts and experienced doctoral/post-doctoral researchers with frames from 5 different international centres and multi organs targeting multiple populations and varied endoscopy video modalities associated with pre-malignant and diseased regions as follows: Organ 1: Colon-rectal, associated disease: polyp, cancer Organ 2: Oesophagus, associated disease: Barrett’s, dysplasia and cancer Organ 3: Stomach and duodenum, associated disease: pyloric inflammation, dysplasia, cancer
