DETECTION OF BLOOD VESSELS IN RETINA TO DIAGNOSE RETINOPATHY FROM RGB RETINA MODEL. GOBAR FILTER WITH LOCAL ENTROPY THERSHOULDING FOR VESSELS SEGMENTATION UNDER VARIOUS NORMAL OR ABNORMAL CONDITIONS.
3. Detection of Blood Vessels in Retina to diagnose Diabetic
Retinopathy from RGB Retina model.
It is complicated due to presence of bright and Dark tissues in
Retinal images.
Gabor Filter with local entropy thresholding for vessels
segmentation under various normal or abnormal conditions.
Method can be applied for image registration purpouse to
monitor Diabetic Retinopathy.
The performance of the proposed algorithm is evaluated by
MATLAB
OCET 3
9. Obtain all the inputs
Pre process the inputs
Process each contextual region thus
producing grey level mapings
Interpolate grey level mappings in
order to assemble final clache image

11. The Gabor Filter introduced by Dennis Gabor
Linear filter used for texture analysis
Frequencies content in image in specific direction
in localised region around the point

14. Thresholding an image that
selects an optimum
threshold value
By choosing pixel intensity
from image's histogram
That exhibit maximum
entropy over the entire
image.

15. Low Noise
High Accuracy
Better visual Quality’
Low Probabiity of Error
OCET 15
16. Analysis manifests maximum true positive rate and
reduces false vessels detection in the fundus.
