Endoscopic surgery is carried out without any direct visual contact with the operation area.The surgeon will perform operations by just looking on the monitor screen of the computer.The operation area is displayed on a monitor for visual feedback.During the course of an operation,image quality may be low due to degradations of the endoscopic images.The goal of our research is to enhance the endoscopic image by using total variation texture enhanced image decomposition technique.Several papers address the topics highlight detection and substitution of missing image data,but we do not know of any research group working on general endoscopic image enhancement. In this book we describe the texture enhanced histogram equalization method to enhance endoscopic images.
