Abstract

The invention discloses an eye fundus image splicing method and system, and the method comprises the steps: reading a plurality of collected eye fundus images, and selecting one eye fundus image fromthe plurality of eye fundus images as an optimal reference image for image registration; Carrying out blood vessel image extraction on the optimal reference image by adopting a blood vessel extractionalgorithm based on a Segnet image segmentation model, obtaining a corresponding optimal reference blood vessel image, carrying out blood vessel image extraction on each of the rest eye fundus images,and obtaining a corresponding eye fundus blood vessel image as a to-be-registered image; Based on the logarithmic polar coordinates, performing image registration on each to-be-registered image and the optimal reference blood vessel image to obtain a corresponding registered image; And for the plurality of registered image images, carrying out weighted fusion on the plurality of registered imageimages by adopting a pixel value weighted fusion method based on a distance matrix to obtain a final fundus image splicing image. The quality of the stitched image is effectively improved, and the problem that a traditional fundus image stitching method has a certain limitation is solved.

Description

technical field [0001] The invention relates to the technical field of medical image processing, in particular to a fundus image stitching method and system. Background technique [0002] Neonatal fundus images are an objective and standard auxiliary diagnostic method in neonatal ophthalmology. As the only blood vessels that can be directly observed in the whole body, retinal blood vessels are effective indicators for evaluating the microvascular function of the whole body, and the inspection method is simple and noninvasive. Therefore, the fundus images of newborns can not only record the eye conditions of newborns at birth, but also facilitate remote consultation and preserve evidence-based medical evidence, providing a wealth of information for newborn eye disease screening, retinal disease diagnosis and treatment, and pathological mechanism exploration. Information. In the process of taking fundus images, because the color of the retina of the fundus of newborns is ligh...
