Early and accurate diagnosis of gastrointestinal diseases is key to increase patient survival chances. An efficient screening is key to locate the precursor lesions. Videocolonoscopy and wireless capsule endoscopy (WCE) are the gold standard tools for colon and intestinal tract screening, respectively. These tools still present some drawbacks such as lesion miss-rate, lack of in-vivo diagnosis capabilities or perforation risk. CAD systems can play a key role to assist clinicians in the different stages of the exploration. The objective of Gastrointestinal Image ANAlysis (GIANA) Workshop is to gather researchers working in this topic and to discuss with them the most recent state-of-the-art approaches, including those clinical aspects that are needed to efficiently deploy these systems in the exploration room.
The main topics of the workshop are the following: • lesion detection and localization (colonoscopy videos and wireless capsule endoscopy images) • lesion classification (colonoscopy images, wireless capsule endoscopy images) • anatomical structures segmentation (polyps, blood vessels, inflammatory structures, luminal region) • image classification (image quality, presence of bleeding) • instrument detection, localization and segmentation • quality assessment • application of new imaging modalities (NBI, FICE, iSCAN)
