Purposes:This paper puts forward a robust method of fast detection of vessel skeleton in retinal images for quantitatively analysing subtle morphological changes in retinal vessels.Methods:1 Image preprocessing(De noising,Image enhancement).2 Fast detection of retinal vessels was achieved by performing 2 D Gaussion matched filters only on the mask images (binarized and dilated gradient image).3 Postprocessing(vessel thinning,et al).Results:The performance of the method was compared with those of the traditi...
