Sharib Ali, Felix Zhou, Christian Daul (Eds.) Proceedings of the EAD 2019 Workshop on Endoscopic Artefact Detection Challenge Co-located with the 16th International Symposium on Biomedical Imaging (ISBI) Venice, Italy, April 8, 2019 https://biomedicalimaging.org/2019/challenges/ Preface Endoscopy is a widely used clinical procedure for the early detection of numerous cancers (e.g., nasopharyngeal, oesophageal adenocar- cinoma, gastric, colorectal and bladder cancers) therapeutic proce- dures and minimally invasive surgery (e.g., laparoscopy). A major drawback of endoscopy video frames is that they are heavily cor- rupted with multiple imaging artefacts (e.g., pixel saturations, mo- tion blur, defocus, specular reflections, bubbles, fluid and debris). These artefacts not only present difficulty in visualizing the underly- ing tissue during diagnosis but also affect any post-analysis methods such as lesion detection and video image retrieval required for infor- mative reporting and follow-ups. Accurate detection of artefacts is therefore a core challenge in a wide-range of endoscopic applications across multiple disease areas. The precise detection of endoscopic artefacts is crucial to achieve high-quality endoscopic frame restora- tion and necessary to realize reliable computer assisted endoscopy tools for improved patient care. Together with six international clinical data providers, we col- lated a large set of multi-organ, multi-modal and multi-population endoscopy video frames corrupted with different artefacts. Gold stan- dard ground truths were established and made publicly available to the community. This challenge comprised of three sub-challenges: 1) detection, 2) semantic segmentation and 3) detection generaliza- tion. All algorithms were evaluated online with the same evaluation metrics. We attracted nearly 29 AI algorithm developers and 529 enthusiasts to participate in the EAD2019 challenge. This volume contains the proceedings of the first edition of the EAD challenge workshop, which was held in Venice, Italy, on April 8, 2019 co-located with the 16th International Symposium on Biomed- ical Imaging (ISBI). This editiion of the EAD workshop has been compiled from the 10 accepted papers submitted by top performing teams (12 out of 29) in an endoscopy artefact detection challenge1 . Each paper was reviewed by at least 2 reviewers in the field.
