Detection and Classification of Retinal Fundus Images Exudates using Region based Multiscale LBP Texture Approach

Diabetic retinopathy (DR) is one of the most important cause of vision loss in diabetic patients. The most primary sign of DR is the presence of exudates, and detecting these in early screening is crucial in preventing vision loss. This paper proposes a system for automatic exudate detection using a combination of texture features, extracted from different local binary pattern (LBP) variants, with an artificial neural network (ANN) classifier. The publicly available database DIARETDB0 of colour fundus images was used for testing purposes and the values of sensitivity, specificity and accuracy found were 98.68%, 94.81 % and 96.73% respectively for the neural network based classification. These results have also been shown to outperform existing work.
