Abstract

The wireless capsule endoscopy (WCE) imaging technique provides detailed images of the gastrointestinal (GI) tract, in particular the small intestine, not feasible with earlier techniques. We present a model of deformable rings (MDR) for aiding in the interpretation of WCE videos. The model flexibly matches consecutive video frames with regard to displacement of distinctive portions of the GI tract?s tube-like surface. It creates a map, 2D representation of the surface, and estimates relative velocity of a capsule endoscope as it traverses the GI tract. The map can be glanced through for rapid identification of the possible abnormal areas for further detailed endoscopic video investigation. This method significantly reduces the total time spent in interpretation of the WCE videos.
