FCM clustering segmentation with different subimage sizes. (a) Original retinal image. (b) Zooming into the exudates region. (c) Segmentation result of original image using FCM. (d) Segmentation result with the subimage size of 1520 pixels. (e) With the subimage size of 3040 pixels. (f) With the subimage size of 6080 pixels. Note: the background is filled with black.
