Abstract

The invention discloses a dual-model-based fundus image quality evaluation method and device and a related medium, and the method comprises the steps: obtaining a batch of fundus images, and selecting a target image; extracting first local information from the target image by using a ResNet50 network, and extracting first global information from the target image by using a ViT network; predicting based on the first local information and the first global information to obtain an image quality evaluation result of the target image so as to construct an image quality evaluation model; evaluating the next image by using the image quality evaluation model to obtain image quality difference information; and utilizing a loss function to respectively constrain the image quality evaluation result and the image quality difference information. According to the method, multi-task learning is carried out on the fundus image based on double models, the fundus image is evaluated in a local and global combined mode, and meanwhile, the quality evaluation effect of the fundus image is improved by utilizing difference information between different fundus images.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method, device and related medium for evaluating the quality of fundus images based on dual models. Background technique [0002] Fundus images are captured by ophthalmologists through professional fundus cameras, including optic cup, optic disc, macula, exudates and retinal blood vessels and other physiological structures. It is an important medical image and is widely used in auxiliary medical diagnosis. The current clinical diagnosis of fundus diseases is mainly made by ophthalmologists through observation and analysis of the patient's fundus images or eyeballs to make subjective judgments, by observing whether there are hard exudates, soft exudates, microaneurysms and Bleeding can help determine whether a patient has diabetic retinopathy, and glaucoma can be judged by observing the size and position of the optic disc in the fundus image. Cardiovascular dis...
