and judging whether the vertex of the parabola falls in the original fundus image, and if the vertex of the parabola falls in the original fundus image, defining the vertex of the parabola as the center of the optic disc.
Macular location based on appearance and structural features: according to the position relation between the macula lutea and the optic disc, firstly, the searching range of the fovea centralis is further narrowed on the basis of the determined optic disc center. In a preferred mode, because the distance between the fovea centralis of the macula and the center of the optic disc is generally 2 times to 3 times of the diameter of the optic disc, an annular mask is constructed by taking the center of the optic disc as the center of a circle and is defined as a fovea searching range; and then, in the search range area, positioning the fovea according to the characteristic that the brightness of the fovea is the lowest. In a preferred mode, a fast searching mode based on brightness contrast among the regions is adopted to determine the position of the fovea; and finally, according to the brightness information, taking the fovea centralis as the center of a circle and fitting the macular region in a circular manner.
