AIM
To identify diabetic retinopathy using the retinal images in an
efficient manner.
Exudates is one of the features used to identify the
diabetic retinopathy .

INTRODUCTION-EYE
INTRODUCTION-DIABETIC
RETINOPAHTY
DIABETIC RETINOPATHY
• DR is an eye disease which has been caused due to high blood
sugar level.
TYPES OF DR
ADVANTAGES:
The low contrast retinal image- intensity increased
and a
number of edge pixels were extracted.
DISADVANTAGES:
More time consuming.

contribution of image processing to the diagnosis of
diabetic retinopathy thy,detection of exudates in colour
fundus images of the human retina".
ADVANTAGES:
Time consumption reduced as it uses mathematical
is morphology
techniques .
DISADVANTAGES:
The paper ignored some types of errors on the border
of the segmented exudates in their reported performances.
Time consumption is reduced but not to great extent. 8

CONCLUSION
• The selected features clustered by k-means clustering and
classified into exudates and non –exudates using naive
bayes classifier.
• Using this approach, the exudates are detected with 98%
success rate.
