A retinal image has blood vessels, optic disc, fovea, and so forth as the main
components of an image. Segmentation of these components has been investigated
extensively. Principal component analysis (PCA) is one of the techniques that
have been applied to segment the optic disc, but only a limited work has been
reported. To our knowledge, fovea segmentation problem has not been reported in
the literature using PCA. In this paper, we are presenting the segmentation of
optic disc and fovea using PCA. The PCA was trained on optic discs and foveae
using ten retinal images and then applied on seventy retinal images with a
success rate of 97% in case of optic discs and 94.3% in case of fovea.
Conventional algorithms feed one patch at a time from a test retinal image, and
the next patch separated by one pixel part is fed. This process is continued till
the full image area is covered. This is time consuming. We are suggesting
techniques to cut down the processing time with the help of binary vessel tree of
a given test image. Results are presented to validate our idea.
