Paper Details

Location of macula is roughly in the center of the retina, and sequential to the optic nerve. Macula is verysensitive part of the retina which is responsible for the detailed central vision. At the center part of the macula there isfovea. Because of the macula we are able to see the detail things and we can able to perform task which require centralvision like reading. Localization of Macula plays an important role to detect Diabetic retinopathy, macular oedema,glaucoma etc. For localization of macula we have used the novel approach. We have performed the steps like firstly RGBimage is taken as input image, then green channel of RGB image is extracted. After green channel extraction contrastlimited adaptive histogram equalization is done for image enhancement. Morphological opening and closing is appliedon enhanced image. After Morphological operation thresholding is applied. Then multilevel two dimensional waveletdecomposition is done using new designed wavelet ( named as DR wavelet) and haar wavelet and macula is extractedsuccessfully. Using speed up robust feature localization of macula is done. For this work we have used three databaseswhich are publically available that are DIARETDB0, DIARETDB1 and HRF database having 130, 89, 45 fundus imagesrespectively.
