ABSTRACT

The Retinex theory is used to deal with the removal of unfavorable illumination effects from images. In this paper, we present the Retinex theory for bleeding detection in wireless capsule endoscopy (WCE). This processing is quite appropriate to refresh old bleeding region and bleeding region in shadow. A novel total variation model (TV-Retinex) is proposed to solve the Retinex problem quickly; also a support vector machine is employed for classification. Experimental results demonstrate the efficacy of the proposed method.
