Abstract EN
Background.
The aim of this work is to present an automatic colorectal polyp detection scheme for capsule endoscopy.
Methods.
PillCam COLON2 capsule-based images and videos were used in our study.
The database consists of full exam videos from five patients.
The algorithm is based on the assumption that the polyps show up as a protrusion in the captured images and is expressed by means of a P-value, defined by geometrical features.
Results.
Seventeen PillCam COLON2 capsule videos are included, containing frames with polyps, flat lesions, diverticula, bubbles, and trash liquids.
Polyps larger than 1 cm express a P-value higher than 2000, and 80% of the polyps show a P-value higher than 500.
Diverticula, bubbles, trash liquids, and flat lesions were correctly interpreted by the algorithm as nonprotruding images.
Conclusions.
These preliminary results suggest that the proposed geometry-based polyp detection scheme works well, not only by allowing the detection of polyps but also by differentiating them from nonprotruding images found in the films.
