Impact of the Region of Analysis on the Performance of the Automatic Epiretinal Membrane Segmentation in OCT Images

Abstract

[Absctract]: The Epiretinal Membrane (ERM) is an ocular pathology that can cause permanent visual loss if left untreated for long. Despite its transparency, it is possible to visualise the ERM in Optical Coherence Tomography (OCT) images. In this work, we present a study on the impact of the analysis region on the performance of an automatic ERM segmentation methodology using OCT images. For this purpose, we tested 5 different sliding windows sizes ranging from to pixels to calibrate the impact of the field of view under analysis. Furthermore, 3 different approaches are proposed to enable the analysis of the regions close to the edges of the images. The proposed approaches provided satisfactory results, with each of them interacting differently with the variations in window size.
