Capsule Endoscopy (CE) is a new endoscopic system for convenient and accurate investigation of small bowel pathology including obscure gastrointestinal bleeding without invasive surgery. We have developed a technique to detect the bleeding automatically utilizing color spectrum transformation (CST). The detection method in this paper include parameter compensation step which compensate irregular image condition using color balance index. The feature value is extracted from each image and used in CST method as parameter compensation constant. Experimental results show the proposed method achieves (before patient adaptive method : 80.87%, 74.25%, after patient adaptive method : 94.87%, 96.12%) of sensitivity and specificity. |
