Method of retinal vessel segmentation based on Gabor wavelet

In terms of the special gray distribution and region structure in retinal image,a novel blood vessel segmentation method based on Gabor wavelet is proposed.The Gabor wavelet is taken to enhance vessels,then the algorithm based on improved adaptive binarization is employed for the retinal image's binarization processing,and the mathematical morphology is applied to extract the vessels region by analysis of region connectivity.The experiments implemented on the Hoover database indicate the efficiency of the proposed approach,and this blood vessel segmentation method is better than the Hoover algorithm.
