Paper Title
Novel Approach for Macula Localization Using Designed Wavelet and haar wavelet
Abstract
Location of macula is roughly in the center of the retina, and sequential to the optic nerve. Macula is very sensitive part of the retina which is responsible for the detailed central vision. At the center part of the macula there is fovea. Because of the macula we are able to see the detail things and we can able to perform task which require central vision 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 RGB image is taken as input image, then green channel of RGB image is extracted. After green channel extraction contrast limited adaptive histogram equalization is done for image enhancement. Morphological opening and closing is applied on enhanced image. After Morphological operation thresholding is applied. Then multilevel two dimensional wavelet decomposition is done using new designed wavelet ( named as DR wavelet) and haar wavelet and macula is extracted successfully. Using speed up robust feature localization of macula is done. For this work we have used three databases which are publically available that are DIARETDB0, DIARETDB1 and HRF database having 130, 89, 45 fundus images respectively.
KeyWord
Diabetic Retinopathy, Macula, New Designed wavelet, haar wavelet, fundus image.
