Optic disc detection and segmentation using saliency mask in retinal fundus images

•Optic disc localization in fundus color retinal images based on novel saliency map.•Novel blood vessel extraction and inpainting methods from two color channels through morphological operation and thresholding technique.•Optic disc segmentation method based on multiple novel saliency maps.•Implementation of various databases: ChaseDB1, Drive, HRD, Drishti, Drions, Rim-One, IDRID, Bin Rushed, Magrabi, Messidor and a local database.•The proposed methods of optic disc localization and segmentation yield an overall accuracy of 99.80% and 99.63%, respectively, on 2.050 images.
