Findings from University of Saskatchewan Has Provided New Data on Medical Technology

May 30, 2014

By a News Reporter-Staff News Editor at Health & Medicine Week -- Investigators publish new report on Health and Medicine. According to news originating from Saskatoon, Canada, by NewsRx correspondents, research stated, "Wireless Capsule Endoscopy (WCE) is a technology in the field of endoscopic imaging which facilitates direct visualization of the entire small intestine. Many algorithms are being developed to automatically identify clinically important frames in WCE videos."

Our news journalists obtained a quote from the research from the University of Saskatchewan, "This paper presents a supervised method for automated detection of bleeding regions present in WCE frames or images. The proposed method characterizes the image regions by using statistical features derived from the first order histogram probability of the three planes of RGB color space. Despite being inconsistent and tiresome, manual selection of regions has been a popular technique for creating training data in the studies of capsule endoscopic images. We propose a semi-automatic region-annotation algorithm for creating training data efficiently. All possible combinations of different features are exhaustively analyzed to find the optimum feature set with the best performance. During operation, regions from images are obtained by applying a segmentation method."

According to the news editors, the research concluded: "Finally, a trained neural network recognizes the patterns of the data arising from bleeding and non-bleeding regions."
