Detection of Various Anatomical Structures in Retinal Images and Fovea Detection using Wavelets

M. Tamil Nidhi, S. Xavier Arockiaraj


Detection of anatomical structures is one of the most
important areas in ophthalmology. On day today life everyone are
experiencing more defect on retinal areas this paper is a small
contribution for such cases by detecting different features (like blood
vessels, optic disk, macula, fovea etc.) automatically from retinal
image. This presents simple techniques for extracting blood vessels,
some relevant information on optic disk and also mainly focusing on
fovea region and as a further study top hat transformation is been
compared with the results of bottom hat transformation during
extraction of blood vessels. This is compared with wavelets and
which method gives better result is determined. The experimental
results illustrate the usefulness of the new method. Thus the
proposed scheme is robust also.
