Detection of Diabetic Macular Edema in Optical Coherence Tomography Image Using an Improved Level Set Algorithm

Figure 2

Original OCT image was segmented to obtain the ROI region and DME region. (a) Original OCT image; (b) K-means clustering is used for ROI segmentation; (c) SBGFRLS-OCT algorithm is used for DME segmentation. Red lines were used to label the retinal regions (ROI), and green lines were used to label DME regions.
