Compressive Sensing-Based Diagnosis of Diabetic Retinopathy from Fundus Image – A Sparse Approach

Abstract

Diabetic Retinopathy (DR) is an abnormality related with eye. It is caused due to alteration of the blood vessels present in the retina. If this disease is not treated at the early time, it may lead to permanent vision loss. Numerous image processing techniques including Enhancement, Segmentation, Morphology, Image Fusion, Classification and Registration have been enveloped for the early recognition of DR through blood vessels, exudes, hemorrhages and microaneurysms. This paper deals with a new approach for the analysis of proliferate and non-proliferate DR with the help of Compressive Sensing (CS) technique. CS is a sparse way of effective reconstruction of signals that works mainly on two constraints namely sparsity and incoherence. In this paper, various CS-based approaches are applied to fundus image. The results are studied and the best approach is used for Image Segmentation, Feature Extraction and Classification.
