Abstracts
Diabetic retinopathy (DR) is a common retinal complication associated with diabetes.
It is a major cause of blindness in middle as well as older age groups.
Therefore early detection through regular screening and timely intervention will be highly beneficial in effectively controlling the progress of the disease.
Existing method
Thresholding method :
It is easy and fast for us to carry out, this method is deemed as the preprocessing used in conjunction with other methods.
Disadvantage of thresholding segmentation method :
It is not applicable of multi-channel image and characters are not very different from the images, for gray-scale images do not exist significant differences or has a bigger overlap region of gray value images is difficult to get accurate results..
Advantages of proposed
Boundry will be extracted
Exudates region will be cleared
