Abstract
INTRODUCTION: Nowadays, mass screening campaigns for colorectal cancer diagnosis in the early and curable stage is essential yet limited due to many reasons, for example, invasiveness, fear of pain, and embarrassment for patients. Indeed, mass screening programs, allowing precancerous lesion detection, are the most cost-effective way to reduce mortality and potentially eradicate colorectal cancer threat. Accurate localization represents a key element in capsule endoscopy, that is, estimation of position and orientation of endoscopic capsule devices enables enhancement of technological and medical features, such as reliable closed-loop control of active-locomotion capsules, accurate lesions localization, retargeting of pathologies, and follow-up.
