The algorithm is invariant to illumination and works well on poor contrast images with high reflection noise. The artefacts are correctly rejected despite their colour, intensity and contrast being almost similar to that of exudates. Optic disc is localized and segmented using average filter of specially determined size which is an important step in the rejection of false positives. Exudates are located by generating candidate regions using variance and median filters followed by morphological reconstruction. The strategic selection of local properties to decide the threshold, makes this approach novel and adaptive, that is highly accurate for detection of exudates. The proposed method was tested on two publicly available labelled databases (DIARETDB1 and MESSIDOR) and a database from a local hospital and achieved a sensitivity of 96.765% and a positive predictive value of 93.514%.<\/p>","DOI":"10.4018\/ijehmc.2019010102","type":"journal-article","created":{"date-parts":[[2018,9,28]],"date-time":"2018-09-28T14:13:12Z","timestamp":1538143992000},"page":"18-37","source":"Crossref","is-referenced-by-count":2,"title":["An Adaptive Algorithm for Detection of Exudates Based on Localized Properties of Fundus Images"],"prefix":"10.4018","volume":"10","author":[{"given":"Katha","family":"Chanda","sequence":"first","affiliation":[{"name":"College of Computing, Georgia Institute of Technology, Atlanta, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ashish","family":"Issac","sequence":"additional","affiliation":[{"name":"Department of Electronics & Communication Engineering, Amity University, Noida, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Malay Kishore","family":"Dutta","sequence":"additional","affiliation":[{"name":"Center for Advanced Studies, Dr. A.P.J Abdul Kalam Technical University, Lucknow, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2432","reference":[{"key":"IJEHMC.2019010102-0","doi-asserted-by":"publisher","DOI":"10.2337\/dc07-1312"},{"key":"IJEHMC.2019010102-1","doi-asserted-by":"publisher","DOI":"10.1109\/ICMLC.2012.6359522"},{"key":"IJEHMC.2019010102-2","doi-asserted-by":"crossref","unstructured":"Decenciere, E., Zhang, X., Cazuguel, G., Lay, B., Cochener, B., Trone, C., . . .
