Recognition of hemorrhage in the images of wireless capsule endoscopy

Gastrointestinal hemorrhage has always been a difficult problem in clinical practice. The use of wireless capsule was a breakthrough in endoscopic diagnosis of the source of bleeding in small intestine. However, inspection of the capsule record data is a time-consuming process, and its reduction is a very important aspect in urgent cases. This paper provides the method of the hemorrhage recognition in the gastrointestinal tract using a wireless capsule endoscopy. The method is based on analysis of the color scheme HSV [4] (Hue, Saturation, Value). According to this scheme the images of the gastrointestinal tract that are expected to contain hemorrhage are selected. In consequence of the two-stage analysis system (blocks and pixels) a high precision of the study is attained, practically eliminating mistakes. The achieved classification of the images by color code gives a possibility to create a scale of presence or absence of bleeding in each part of the gastrointestinal tract as well as to determine the intensity of hemorrhage.
