Active Blood Detection in a High Resolution Capsule Endoscopy using Color Spectrum Transformation

Capsule Endoscopy(CE) is a new modality for convenient and accurate investigation of small bowel pathology including obscure gastrointestinal bleeding. In this paper, we present a method for automatic detection of the bleeding region for a new high performance CE system with a new feature index in CE. The CE transmits 3 images per second to the receiver for about 10 hours. Over 100,000 images are recorded to the receiver. Typically, viewing such a large amount of images gives clinicians a significant burden [3]. We propose a technique to detect the bleeding automatically, utilizing the color spectrum transformation method and morphological filtering. Also, we can decide bleeding sites effectively through continuous image detection.
