In this paper, we propose an efficient algorithm for highlight removal in endoscope images. According to the analysis the endoscope images are presented by several kinds of regions and the dichromatic reflection model is not valid for the whole image. However it is possible to segment the image using machine learning algorithms and extract only the body and highlight reflection regions for which the dichromatic reflection model is relevant and then the highlight removal technique is applied. We present the experimental results confirming the method's feasibility.
