Abstract

The embodiment of the invention discloses a premature infant retinopathy plus lesion classification method. The method comprises: constructing a blood vessel segmentation model capable of segmenting ablood vessel image from the fundus image; and constructing a classification model capable of carrying out plus lesion classification on the vascular image, segmenting the vascular image in the targetfundus image from the target fundus image by applying the vascular segmentation model, and classifying the vascular image in the target fundus image by applying the classification model to obtain a plus lesion category to which the vascular image in the target fundus image belongs. Therefore, blood vessel segmentation and blood vessel image classification are carried out on the fundus image basedon the blood vessel segmentation model and the classification model, and compared with an existing mode of manually classifying the plus lesions, the classification efficiency of the premature infantretinopathy plus lesions can be improved.

Description

technical field [0001] The invention relates to the field of computers, in particular to a classification method for retinopathy of prematurity plus lesions. Background technique [0002] Retinopathy of prematurity (ROP) is an important blinding eye disease worldwide, accounting for 6% to 8% of the causes of blindness in children. The plus lesion in ROP has important clinical significance for ROP. Plus lesions manifested as a series of clinical manifestations such as vasodilation, tortuosity, vitreous opacity, iris vasodilation, and pupil rigidity in the posterior pole of the retina in ROP. [0003] At present, the identification method of plus lesions in retinopathy of prematurity is to obtain fundus images through a fundus camera, and then ophthalmologists rely on the naked eye to observe the plus lesions and classify the plus lesions. Due to the continuous increase in the prevalence of ROP worldwide, most of the patients do not even receive any form of examination in tim...
