Embodiment 1
[0131] Embodiment 1, the retinal blood vessel automatic segmentation method facing glaucoma clinical diagnosis, such as Figure 1-9 shown, including the following:
[0132] In the present invention, the fundus image is preprocessed first, and then the matching filter, neural network, multi-scale line detection, scale space analysis and morphological model are respectively constructed to initially segment retinal blood vessels, and the average value of the five segmentation results is taken as the preliminary segmentation output in order to reduce noise . Next, a mask was designed to separate the exudates and optic disc regions, the segmentation results of the morphological model were replaced with the white regions of the mask, and the preliminary segmentation outputs were fused to generate combined results. Finally, the prior knowledge of retinal vessels is considered (that is, the retinal vessel network is composed of vessel trees connected with vessel segments), and the fi...
