Computer-Assisted Segmentation of Videocapsule Images Using Alpha-Divergence-Based Active Contour in the Framework of Intestinal Pathologies Detection

Figure 9

WCE image segmentation using the proposed histogram-based active contour approach. ((a) and (b)) Gastric polyps in Peutz-Jeghers syndrome, (c) colon sigmoid polyp, (d) lymphangiectasia, (e) small-bowel metastasis, (f) radiation enteritis, (g) angiodysplasia, (h) lipoma, and (i) hypertrophied anal papilla. For each segmentation result, indicated values of alpha correspond to the optimal value at convergence of the optimisation process.
