Optic disc segmentation based on variational model with multiple energies

作者：

Highlights：

• A sparse coding based method is designed to localize the optic disc (OD) in fundus image.

• Variational model integrating three energy terms is proposed to segment OD boundary.

• Phase-based edge stop function is designed in the boundary energy.

• The proposed method is evaluated and analyzed on three public databases and outperforms the state-of-the-art approaches.
