Identification of Vessels from Retinal Image Analysis
Retinal Blood vessel morphology can be an important indicator for many diseases such as diabetes mellitus, hypertension and arteriosclerosis. The measurement of geometrical changes in retinal veins and arteries can be applied to a variety of clinical studies. The spotlight of this paper is developing the screening system with the aim of highly accurate and automated analysing tool for the ophth...
متن کاملReconstruction of the Human Retinal Blood Vessels by Fractal Interpolation
This paper presents the fractal interpolation method of the human retina image. In the first part, we focus on the segmentation image with Skeletonization and identify different types of pixels. Secondly, using Douglas-Peucker algorithm to reduce the number of pixels in the image we try to keep a form close to the original. then, we used fractal interpolation( IFS ) to decompress the encoded im...
متن کامل[Avulsed retinal vessels].
PURPOSE To describe the clinical evolution of cases with avulsed retinal vessels without retinal detachment treated with laser or scleral buckle. METHODS Retrospective analysis of cases with avulsed retinal vessels treated between 2001-2003. Laser photocoagulation or scleral buckle was used. The minimum follow-up was 6 months. Average age was 53.6 years. RESULTS Of 13 patients, 8 were photo...
متن کاملAnomalous development of retinal vessels.
MICHAELSON (1954), writing on the retinal blood vessels in man, stated that "an artery crossing an artery, or a vein crossing a vein, has not once been reported, or been personally observed". This is in keeping with the present hypothesis that the development of retinal vessels in vertebrates is stimulated by a local intraretinal factor. In man, each quadrant of the fundus accumulates, during d...
متن کاملFractal Analysis Reveals Reduced Complexity of Retinal Vessels in CADASIL
The Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL) affects mainly small cerebral arteries and leads to disability and dementia. The relationship between clinical expression of the disease and progression of the microvessel pathology is, however, uncertain as we lack tools for imaging brain vessels in vivo. Ophthalmoscopy is regarded as a win...
