Abstract

Purpose : The detection and classification of retinal lesions play a vital role in screening diabetic retinopathy, one primary cause of visual impairment globally. Extensive research on deep learning has shown their good performance in this area. However, these methods suffer from the image samples’ scarcity and diversity of morphological characteristics. This study aims to establish a binary descriptor-based classification instrument for discriminating the retinopathy slices by leveraging deep backbone models capable of resolving complex cases.

Methods : 4 datasets of retinal slices were collected in this study. In total, there are three types of retinal images used as the input for the proposed deep learning-based pipeline, which consists of 3 phases (as shown in Fig. 1):
We added affine transformations to the raw samples.
What fed the original and deformed retinal images into one backbone model.
The generated feature for each slice was fed into a non-linear classifier to discriminate three categories of diabetic cases.
Note that three constraints, including affine transformation in variation, even distributed, and quantization loss minimization was imposed on the features rendered as a binary descriptor. The structure of the proposed approach is shown in Figure 1.

Results : The proposed framework is superior to the state-of-the-art algorithms in accuracy, sensitivity, and precision. The ten-fold cross-validation accuracy of the presented approach on the samples is 98.35%.

Conclusions : The findings indicate that the proposed approach is a potentially helpful instrument for retinal lesion identification. By constraining the output features extracted from the input images it not only can increase the generalization of the deep learning models but also guarantee accuracy.
