A Multi-Scale Feature Fusion Method Based on U-Net for Retinal Vessel Segmentation

Abstract: Computer-aided automatic segmentation of retinal blood vessels plays an important role in the diagnosis of diseases such as diabetes, glaucoma, and macular degeneration. In this paper, we propose a multi-scale feature fusion retinal vessel segmentation model based on U-Net, named MSFFU-Net. The model introduces the inception structure into the multi-scale feature extraction encoder part, and the max-pooling index is applied during the upsampling process in the feature fusion decoder of an improved network.

“…Literature shows that models incorporating multi-scale features perform better at segmentation. 20 In conclusion, a 2D U-Net was implemented and trained on OCT b-scans for the segmentation of the follicular structure and surrounding non-follicular tissue. The method allowed a fast and reliable segmentation of the tissue microstructure, without the need for user intervention.…”

“…Based on the advantages of the U-Net network in medical images, many experts and scholars have proposed improvements to the U-Net model. [10][11][12][13] In this paper, we propose a dense connected U-Net retinal vessel segmentation algorithm based on multiscale feature convolution extraction. The proposed algorithm adopts Inception and dense block structure on the basis of U-Net.…”

“…ere are some limitations, such as insufficient segmentation degree and poor continuity of microretinal vessels, which cannot meet clinical diagnosis needs. e U-Net model has been applied to the segmentation of medical images for years, and many improved structures based on the U-Net model [29][30][31][32][33][34][35][36] have achieved good segmentation results. In this paper, we explore an automatic segmentation algorithm of retinal vessels based on improved U-Net.…”
