The strategy involves the applications of fuzzy c-means clustering, edge detection, otsu thresholding and inverse surface thresholding. The main advantage of the proposed approach is that it does not depend on manually selected parameters that are normally chosen to suit the tested databases. When applied to two sets of databases the proposed method outperforms methods based on watershed segmentation and morphological reconstruction. The proposed method obtained 98.2 and 90.4 in terms of sensitivity for Standard Diabetic Retinopathy Database – Calibration Level 1 (DIARETDB1) and a local dataset provided by National University Hospital of Malaysia (NUHM), respectively. 2013-05-15T06:46:49Z 2013-05-15T06:46:49Z 2012-07 Article Measurement, vol. 45 (6), 2012, pages 1599–1608 0263-2241 http://www.sciencedirect.com/science/article/pii/S0263224112000954 http://dx.doi.org/10.1016/j.measurement.2012.02.016 http://hdl.handle.net/123456789/25488 en Elsevier B.V.
