What is A novel retinal image segmentation using rSVM boosted convolutional neural network for exudates detection about?

Retinal image analysis is an emerging research field in ophthalmological disease diagnosis since falsely detected optic disc, fovea, and blood vessels have become essential levels for automated diagnosis practices. In this article, we introduce a novel retinal image segmentation based on ranking support vector machine (rSVM) with convolutional neural network in deep learning field for the detection of diabetic retinopathy. Firstly, the spatial features of the retinal images have been extracted from RGB channel and mapped into a single binary features plane by the computing of pixel by pixel score using rSVM. Thereafter, we have designed a deep convolutional neural network for the retinal image segmentation followed by automatic anomaly detection using morphological operations. The rSVM computes a score function which is more suitable for multi-level classification to binary features classification in order to reduce the overall execution time in the segmentation task. The CNN has been designed with rSVM to define a consistent feature label in the network that reduces the number of channels in the CNN which lead to fast convergence. As a consequence, we have achieved good segmentati
