Automated segmentation of the optic disc from fundus images using an asymmetric deep learning network

作者:

Highlights:

• A novel deep learning network was proposed based on the classical U-Net model to accurately segment the optic disc from colour fundus images.

• A sub-network and a decoding convolutional block were introduced to provide additional key features and highlight the morphological changes of the target objects in convolutional feature maps.

• Experiment results on both the global field-of-view fundus images and their local disc versions from the MESSIDOR, ORIGA, and REFUGE datasets demonstrated that the developed network achieved promising performance and outperformed some existing segmentation networks.
