Blood Vessel Segmentation in Retinal Fundus Images
The segmentation of retinal blood vessels in the retina is a critical step in diagnosis of diabetic retinopathy. In this paper, we present a new method for automatically segmenting blood vessels in retinal images. Five basic algorithms for segmenting retinal blood vessels, based on different image processing techniques, are described and their strengths and weaknesses are compared. A hybrid alg...
متن کاملEvaluation of the Zeiss retinal vessel analyser.
AIM To investigate the reproducibility and sensitivity of the Zeiss retinal vessel analyser, a new method for the online determination of retinal vessel diameters in healthy subjects. METHODS Two model drugs were administered, a peripheral vasoconstrictor (the alpha receptor agonist phenylephrine) and a peripheral vasodilator (the nitric oxide donor sodium nitroprusside) in stepwise increasin...
متن کاملContinuous retinal vessel diameter measurements: the future in retinal vessel assessment?
PURPOSE To establish an alternative method, sequential and diameter response analysis (SDRA), to determine dynamic retinal vessel responses and their time course in serial stimulation compared with the established method of averaged diameter responses and standard static assessment. METHODS SDRA focuses on individual time and diameter responses, taking into account the fluctuation in baseline...
متن کاملBlood vessel diameter Measurement on retinal Image
Accurate measurement of vessel diameters on retinal images plays an important part in diagnosing cardiovascular diseases and early signs of certain systemic diseases, such as diabetes and hypertension. In this study we develop new method based on computer aided to determine the width of retinal blood vessels by analysing the color fundus image. Retinal vessel diameter was measured based on bloo...
متن کاملDirect measurement of retinal vessel diameter: comparison with microdensitometric methods based on fundus photographs.
A new method for the direct measurement of retinal vessel diameter was developed and the results were compared with those of two computer-assisted semiautomatic microdensitometric methods. The direct measurement method was based on automated detection of vessel edges by processing the one-dimensional retinal image obtained by a linear image sensor set in a fundus camera; results are obtained in...
