Abstract

Wireless Capsule Endoscopy (WCE) allows direct visual inspecting of the full digestive system of the patient without invasion and pain, at the price of a long examination by physicians of a large number of photographs. This research presents a new approach to color extraction to differentiate bleeding frames from normal ones and locate more bleeding areas. We have a dual-system suggestion. We use entire color information on the WCE pictures and the pixel-represented clustering approach to get the clustered centers that characterize WCE pictures as words. Then we evaluate the status of a WCE framework using the nearby SVM and K methods (KNN). The classification performance is 95.75% accurate for the AUC 0.9771% and validates the exciting performance for bleeding classification provided by the suggested approach. Second, we present a two-step approach for extracting saliency maps to emphasize bleeding locations with a distinct color channel mixer to build a first-stage salience map. The second stage salience map was taken with optical contrast.We locate bleeding spots following a suitable fusion approach and threshold. Quantitative and qualitative studies demonstrate that our approaches can correctly distinguish bleeding sites from neighborhoods.

Introduction The invention of fiber-optic endoscopy allowed for the external visualization of the gastrointestinal tract (GI) but was linked with pain and patient distress. The wireless endoscopy of capsules improves greatly in diagnostic endoscopy, without pain, anesthetic, or air-breathing, when testing the human GI tract. Espe¬cially when the source of obscure gastrointestinal ∗Corresponding author. Dr. Ashok Vajravelu, Faculty of Elec¬trical and Electronic Engineering, UniversitiTun Hussein Onn, Malaysia.

At an estimated 35,000 per patient, the health budget has a significant economic impact, accounting for around 5 percent of all GI hemorrhages [1, 2]. The ability to picture the whole small bowel directly is an advance in diagnosing OGB. The time taken by image screening requires clini-cians to look at 14,400–72,000 collected frames, only 1% of which may have clinical interest, which is a major drawback to the CE technique, which influ¬ences a right diagnosed approach [3].
