Illumination Estimation in Capsule Endoscopy Images


Wireless capsule endoscopy (WCE) is a revolutionary imaging method for visualizing gastrointestinal tract in patients. Each exam of a patient creates large-scale color video data typically in hours and automatic computer aided diagnosis (CAD) are of important in alleviating the strain on expert gastroenterologists. In this work we consider an automatic contrast enhancement method for WCE videos.

Example Illumination Correction Results:

The following examples illustrates the proposed SOCTM based contrast tone mapping [1] for Capsule Endoscopy image:
