Localization of optic Disc using New Designed Wavelet
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 9
Abstract
Optic disc is the raised part on the retina which is at the entry part of optic nerve. Optic Disc is yellow in color and it sends the signal towards brain. It is the center point of retina. Optic disc is origin were blood vessels are grown .Optic disc localization is very important part for developing screening system of diabetic retinopathy. Localization of optic disc is also helpful to detect the retinal feature like macula and fovea. It is also helpful in the detection of exudates. In exudates detection, optic disc should be eliminate first. In this work we have used the novel approach for localization of optic disc. We have used following steps to localize optic disc. Firstly we have converted RGB image to red channel. Then Contrast Limited Adaptive Histogram Equalization is used for enhancing the image quality. After image enhancement morphological opening and closing operations are performed and adjusted the image intensity value for increasing the contrast of image. Then multilevel two dimensional wavelet decomposition is done using new designed DR wavelet and optic disc is extracted successfully. Using speed up robust feature localization of optic disc is done. For this work we have used three databases which are publically available that are DIARETDB0, DIARETDB1 and HRF databases having 130, 89, 45 fundus images respectively.
