[IEEE 2018 Chinese Control And Decision Conference (CCDC) - Shenyang (2018.6.9-2018.6.11)] 2018 Chinese Control And Decision Conference (CCDC) - Optic disc segmentation method based on low rank matrix recovery theory

摘要： Optic disc(OD) detection and segmentation is one of the key elements for automatic retinal disease screening systems. This paper proposes an optic disc segmentation algorithm. The unified method based on low rank matrix recovery theory is used to make a significant detection. Then Hough transform is combined to obtain the final segmentation results. The proposed algorithm has short computation time and low complexity. It is robust to variable image illuminations and angles. The algorithm achieves the OD segmentation accuracy of 92.9% of the images on the MESSIDOR public dataset.
