Creating Retinal Fundus Maps
A 'Fundus Map' is a computer generated montage combining multiple adjacent retinal images. It is useful for illustrating large retinal areas. This article describes the history, ethics and methods of producing large area fundus images, and concludes with a tutorial on constructing your own fundus map using Adobe Photoshop.
متن کاملFundus autofluorescence imaging of retinal dystrophies
Fundus autofluorescence (FAF) is a non-invasive imaging technique that enables the visualization of lipofuscin changes in the retinal pigment epithelium. This study aims to illustrate the spectrum of FAF changes in a variety of retinal dystrophies. For this purpose, we examined patients with retinal dystrophies such as Stargardt disease, Best vitelliform macular dystrophy, and retinal dystrophi...
متن کاملAutomatic Generation of Synthetic Retinal Fundus Images
This study aims to generate synthetic and realistic retinal fundus colour images, similar in characteristics to a given dataset, as well as the values of all morphological parameters. A representative task could be, for example, the synthesis of a retinal image with the corresponding vessel tree and optic nerve head binary map, measurement of vessel width in any position, fovea localisation and...
متن کاملModel Based Segmentation for Retinal Fundus Images
This paper presents a method for detecting and measuring the vascular structures of retinal images. Features are modelled as a superposition of Gaussian functions in a local region. The parameters i.e. centroid, orientation, width of the feature are derived by a minimum mean square error (MMSE) type of spatial regression. We employ a penalised likelihood test, the Akakie Information Criteria, t...
متن کاملRetinal Fundus Biometric Analysis for Personal Identifications
In this paper a biometric system for personal identification, realized through the manipulation of retinal fundus images and the detection of its bifurcation points, is described. In the image pre-processing step, a strong contrast exaltation between blood vessels and the background in retinal image is carried out; then blood vessels are extracted and next the vasculature bifurcation and crosso...
