Bleeding Detection through Wireless Capsule Endoscopy (wce)
The wireless capsule endoscopy (WCE), is an imaging technology which is recently established and doesn’t require any wired device. This device detects abnormalities in GI tract i.e.( colon, esophagus, small intestine and stomach). A WCE video consists of 57000 images. It is very hard to examine by clinicians. To determine bleeding images out of fifty seven thousand WCE images makes the task ver...
متن کاملComputer-assisted bleeding detection in wireless capsule endoscopy images
Wireless capsule endoscopy (WCE) has revolutionized the diagnosis and treatment of gastrointestinal tract, especially the small intestine where traditional endoscopies can not reach. However, this new technology leads to the inspection of a large number of images, which is a time consuming process and also too hard by naked eyes for doctors. In this article we propose a new computerized method ...
متن کاملBleeding and Ulcer Detection Using Wireless Capsule Endoscopy Images
Wireless capsule endoscopes (WCEs) have been used widely to detect abnormalities inside regions of the small intestine that are not accessible when using traditional endoscopy techniques. However, an experienced clinician must spend an average of 2 hours to view and analyze the approximately 60,000 images produced during one examination. Therefore, developing a computeraided system for processi...
متن کاملBleeding Detection Algorithm for Capsule Endoscopy
Automatic detection of bleeding is of practical importance since capsule endoscopy produces an extremely large number of images. Algorithm development of bleeding detection in the digestive tract is difficult due to different contrasts among the images, food dregs, secretion and others. In this study, were assigned weighting factors derived from the independent features of the contrast and brig...
متن کاملCluster-based Sampling and Ensemble for Bleeding Detection in Capsule Endoscopy Videos
We present a cluster-based sampling and ensemble method to learn from large, imbalanced data set for bleeding detection in CE videos. Our method selects training examples randomly according to the data distributions derived from clustering. Multiple training sets are created such that data balance is restored. The sampling probability is proportional to the cluster distribution, and within each...
