Ophthalmic reference image selection

-40 OPHTHALMIC REFERENCE IMAGE SELECTION A method for selecting a representative image of an eye from a plurality of captured images, comprises associating (210) neighbouring images from the plurality of images 5 with each other to determine a spatial relationship (shift) of the images and an initial quality value for each image. The method determines an accumulated quality value for at least one portion of each image using the initial quality values corresponding to those other images of the plurality of images that are spatially related with the portion. The spatial relationship between a portion of an image and the other images is identified based of the 10 determined spatial arrangement of the images. The method selects a representative image from the plurality of images using, for each image, at least the initial quality value for the image and the accumulated quality value of at least one portion of the image.
