Comparison of segmentation performance of the SBGFRLS-OCT algorithm against C-V, GAC, and SBGFRLS algorithms. DME segmentation in the OCT image was conducted using C-V, GAC, SBGFRLS, and SBGFRLS-OCT algorithms to obtain ROI and DME region. The four images showed the segmentation results. Red lines were used to mark the retinal region (ROI). Green lines were used to mark the DME regions.
