Diabetic retinopathy causes blindness due to the physiological changes in the retina of human eye, which occurs due to the progression of diabetes. Diabetic retinopathy images differ from normal fundus images by lesions such as: microaneurysm, hemorrhages, exudates, cotton wool spots and variations in blood vessels etc. Appearance of these features on the(More)
Diabetic retinopathy (DR), a complication due to diabetes, is the leading cause of blindness. Diagnosis of DR at its earliest is thus very necessary. In this paper, we present an automated computer aided method for detection of hemorrhages using fundus images. In the first stage, blood vessel (BV) is detected and eliminated. In the following stage(More)
Prolonged diabetes causes severe damage to the vision through leakage of blood and blood constituents over the retina. The effect of the leakage becomes more threatening when these abnormalities involve the macula. This condition is known as diabetic maculopathy and it leads to blindness, if not treated in time. Early detection and proper diagnosis can help(More)
Glaucoma is a chronic eye disease that causes blindness. It is the one of the most common causes of blindness in the world. It results in the loss of vision which cannot be regained. Although glaucoma is not curable, detection of the disease in proper time can stop its further progression. The optic disk (OD), optic cup (OC) and neuroretinal rim (NRR)(More)
Heart failure and heart diseases are among the main causes of death in the world. Therefore it is necessary to have proper tools to determine the heart condition of the patient. ECG is considered to be the most efficient diagnostic tool to check the functionality of the heart. Hence accurate analysis of ECG signal is important. But it is difficult to(More)
For the diagnosis of several retinal diseases, such as Diabetic Retinopathy (DR), Diabetic Macular Edema (DME), Age-related Macular degeneration (AMD) detection of macula and fovea is considered as an important prerequisite. If any abnormality like haemorrhages, exudates fall over macula then vision is severely effected and at higher stage people may become(More)
Glaucoma is one of the most common causes of blindness in the world. The vision lost due to glaucoma cannot be regained. Early detection of glaucoma is thus very important. The Optic Disk(OD), Optic Cup(OC) and Neuroretinal Rim(NRR) are among the important features of a retinal image that can be used in the detection of glaucoma. In this paper, a(More)
