Segmentation of the Blood Vessel and Optic Disc in Retinal Images Using EM Algorithm
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2015, Vol 17, Issue 6
Abstract
Abstract: Diabetic retinopathy (DR), glaucoma and hypertension are eye disease which is harmful and causes pressure in eye nerve and finally blindness. With the invention of new systems and the developing of newtechnologies the research in the medicine field had a great impulse. In particular, the development of the medical imaging field has been revolutionary with the availability of new techniques to acquire and process digital images. This revolution have required of significant innovation in computational techniques for the different aspects of image processing. Retinal image investigation is actually more and more dominant for nonintrusive prognosis approach inside modern day ophthalmology. On this paper, provide a book approach to be able to segment blood vessel and also optic disk inside the fundus retinal photos by making use of EM algorithm. The morphology with the blood vessels and optic disk is actually an essential warning intended fordiseases similar to diabetic retinopathy, glaucoma, and also hypertension. Using this method requires seeing that very first action this extraction with the retina vascular tree when using the graph cut approach. The bloodvessels details is actually next used to appraisal the placement with the optic disk. The optic disk segmentation is carried out utilizing two choice procedures: Expectation maximization (EM) method and morphological operation.
