A methodology for detecting blood-based abnormalities in Wireless Capsule Endoscopy videos

This paper deals with a novel methodology for automatically detecting blood based abnormalities (bleeding, angioectasia and erythema) in wireless capsule endoscopy videos. The methodology is based on a synergistic integration of methods, such as Color K-L transformation, fuzzy region segmentation, Local-Global graphs. The methodology presents several unique features that separate it from the classical bleeding based methods. These features are mainly based on (i) the classification of the blood based pathological cases in three major categories approved by gastroenterologists; (ii) it is based on a synergy of methods tested in the research field for their robustness. Illustrative examples from the methodology are also presented in this paper.
