Saliency based Wireless Capsule Endoscopy Video Abstract

Wireless Capsule Endoscopy (WCE) is a novel revolutionary medical technology obtaining visual information of the entire gastrointestinal, especially the small intestine. However, reviewing a WCE video is a highly time-consuming assignment for the doctors. Focused on the salient region of the WCE images, this paper has proposed a new method to obtain the video abstract. The most representative frames are detected combined mutational and gradient detection. The experiments were performed on 8 video clips and the results demonstrated a promising performance of the proposed method. The average sensitivity, specificity, accuracy and compression are as high as 98%, 84%, 87% and 72%.
