In endoscopic images, significant barrel-type distortions are introduced in case of deploying wide-angle lenses. In this work, the effect of lens distortion correction on the human experts’ classification performance is investigated. Especially, the discrimination between healthy patients and patients suffering from celiac disease is examined. Furthermore, the classification results of human experts are compared with those achieved with state-of-the-art computer aided decision support systems. This paper considers a two- as well as a four-classes case. Finally we come to the conclusion, that distortion correction does not improve the human experts’ classification performance.
