Annotation Tools in Gastrointestinal Polyp Annotation

Ola Selnes et al. Diagnostics (Basel). .

Abstract

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

Keywords: annotation tool; automated labelling; camera capsule endoscopy; computer-aided diagnosis; polyp annotation.
