In this paper, an optic disc segmentation method is proposed based on peripapillary atrophy elimination. The elimination is done through edge filtering, constraint elliptical Hough transform and peripapillary atrophy detection. With the elimination, edges that are likely from non-disc structures especially peripapillary atrophy are excluded to make the segmentation more accurate. The proposed method has been tested in a database of 650 images with disc boundaries marked by trained professionals manually. The experimental results by the proposed method show average m 1, m 2 and m VD of 10.0%, 7.4% and 4.9% respectively. It can be used to compute cup to disc ratio as well as other features for application in automatic glaucoma diagnosis systems. © 2011 IEEE.||Source Title:||Proceedings of the Annual International Conference of the IEEE Engineering in Medicine and Biology Society, EMBS||URI:||http://scholarbank.nus.edu.sg/handle/10635/109747||ISBN:||9781424441211||ISSN:||1557170X||DOI:||10.1109/IEMBS.2011.6091537|
