Optic Disc Localization in Ocular Fundus Images
This paper presents a novel approach to the fast localization and extraction of optic disc from fundus images of the human retina. Optic disc continues to be a major landmark for fundus image registration and is indispensible for the understanding of retinal fundus images. For the detection of optic disc, we first decompose the image into its bit planes. The lower order bit planes are found to ...

متن کاملOcular versus Extraocular Neovascularization: Mirror Images or Vague Resemblances
Sorsby fundus dystrophy (SFD) is an autosomal dominantly inherited degenerative disease of the retina and is characterized by rapid loss of central vision. One of the early signs is the deposition of material in Bruch’s membrane, a five-layered extracellular matrix (ECM) between the retinal pigment epithelium (RPE) and the choriocapillaris. As a hallmark of this condition, there is a high rate ...
