Abstract

The invention provides a retinal fundus image segmentation method and device, which can realize automatic, efficient and accurate segmentation of retinal fundus image blood vessels and optic disks under the condition of only a small number of labeled samples. The method comprises the steps of acquiring a training set image and a corresponding annotation image, wherein the image is a retinal fundusimage; carrying out consistent random cutting and blocking on the obtained training set image and the corresponding annotation image; constructing a U-shaped full convolutional neural network; inputting the randomly clipped and blocked training set images and the corresponding annotation images into a constructed U-shaped full convolutional neural network, and training the U-shaped full convolutional neural network; and segmenting the retinal fundus image by using the trained U-shaped full convolutional neural network. The invention relates to the field of artificial intelligence and diabeticretina diagnosis.

Description

technical field [0001] The invention relates to the fields of artificial intelligence and diabetic retinal diagnosis, in particular to a retinal fundus image segmentation method and device. Background technique [0002] Since retinal fundus blood vessels are the only blood vessels that can be directly observed in a non-invasive way, information such as blood vessels obtained from retinal fundus image segmentation is an important indicator for the diagnosis of diabetic retinopathy. However, manual segmentation of retinal fundus images is time-consuming and laborious. If the method of deep learning is used, a large amount of labeled data is required to complete it. If the number of labeled samples is small, the accuracy of the segmentation of blood vessels and optic discs in retinal fundus images will be poor. However, the width of fundus blood vessels ranges from 1 pixel to 20 pixels, and there are crossings, branches, and centerline reflections of blood vessels. Manual label...
