Automated detection of red lesions in the presence of blood vessels in retinal fundus images using morphological operations

This paper focuses on the automatic detection of retinal abnormalities such as haemorrhages, also known as red lesions from the retinal fundus images. The primary cause of the red lesions in human eye is the disease which is commonly familiar with the name Diabetic Retinopathy, abbreviated as DR. DR is mainly found in people suffering from Type 1 and Type 2 Diabetes. Hypertension is another dominant cause for DR. The proposed technique involves the study of 50 retinal images obtained from the available dataset DIARETDB1.
