Annotation Tools in Gastrointestinal Polyp Annotation

Abstract

International audienceCapsule endoscopy (CE) is a valid alternative to conventional gastrointestinal (GI)endoscopy tools. In CE, annotation tools are crucial in developing large and annotated medicalimage databases for training deep neural networks (DNN). We provide an overview of thedescribed and in-use various annotation systems available, focusing on the annotation ofadenomatous polyp pathology in the GI tract. Some studies present promising results regardingtime efficiency by implementing automated labelling features in annotation systems. Thus, data areinadequate regarding the general overview for users, and may also be more specific on whichfeatures provided are necessary for polyp annotation
