A new retinal enhancement method based on two-scale Gabor filter and morphology is proposed.Firstly,the two-scale Gabor filter is used to extract the major blood vessels and weaken the background.And then the mathematical morphology top-hat transform is used to enhance the image details.Finally,the two methods are integrated to realize enhanced dynamic regulation.The experiments demonstrate that this method can enhance the blood vessels of the retinal images well and weaken the background and noise.which ca...
