Organic Boundary Location Based on Color-Texture of Visual Perception in Wireless Capsule Endoscopy Video

WCE videos about different organs of the digestive system and color change curve in Lab color space around the pylorus. WCE videos are provided by Jinshan. And some sample frames of a video show the results of screening digestive system by WCE. The pylorus is the end of the stomach and the boundary between the stomach and the small intestine, where the color of the images has changed markedly as shown in the a/b color curve. After images have been converted into Lab color space, the a/b color curve is generated by the average values in channel a and b of the continuous images around the pylorus.
