Multie-scale hierarchical feature extraction combined with dilated-residual U-Net for retina automatic segmentation
Journal Title: Eye Science (Yanke Xuebao) - Year 2021, Vol 36, Issue 1
Abstract
[Objective:] To achieve the segmentation of different layers and fluid areas on the optical coherence tomography (OCT) image of the retina. [Methods:] A lightweight neural network based on deep learning was proposed. The network structure adopted in this study was designed based on the architecture of dilated-residual U-Net. By connecting the upsampling output obtained at different depth networks, multi-scale feature fusion was performed to enable the system to accurately identify the boundaries on the OCT image. [Results:] Compared with U-Net, this algorithm could achieve the same accuracy with 1ā2 epochs less, and the accuracy was also improved by 1.25%. [Conclusion:] The proposed network improves the segmentation performance of retinal OCT images, and reduces the number of parameters, which demonstrates the network has great application potential.
