Arteriovenous retinal vascular optic fundus image positioning method

The present invention discloses a disc arteriovenous retinal vascular targeting method of the fundus image, comprising: obtaining a set of global vascular fundus image, according to the global set of vessels in the fundus image of the set of all the vessels; vessels for the global each concentration vessel, fuzzy region of convergence of the convergence algorithm to obtain the blood vessel; count the number of fundus image belongs each pixel area as the convergent voting value of the pixel point; to select a large number of pixels n before the voting value, use of n pixels selected points to obtain a plurality of connected regions eight communication regions communication algorithm, and is the largest area for communication with the disc as the center coordinates of the location information. Disc positioning method of the invention take many positioning ballot, robust, and has good performance in complex situations more lesions in the fundus image, the final position is not added as a template matching convergence correction, the relative does not deal with this methods case of False Rejection less.
