Wireless capsule endoscopy (WCE) is useful to detect abnormal area in human digestive tract. However, many WCE images have low quality such as rather dark and noisy. Pre-processing is an important step in Computer Aided Detection (CAD) system to enhance the quality of WCE images in order to detect t...
