RADNet: Ensemble Model for Robust Glaucoma Classification in Color Fundus Images
share
Glaucoma is one of the most severe eye diseases, characterized by rapid progression and leading to irreversible blindness. It is often the case that pathology diagnostics is carried out when the one's sight has already significantly degraded due to the lack of noticeable symptoms at early stage of the disease. Regular glaucoma screenings of the population shall improve early-stage detection, however the desirable frequency of etymological checkups is often not feasible due to excessive load imposed by manual diagnostics on limited number of specialists. Considering the basic methodology to detect glaucoma is to analyze fundus images for the optic-disc-to-optic-cup ratio, Machine Learning domain can offer sophisticated tooling for image processing and classification. In our work, we propose an advanced image pre-processing technique combined with an ensemble of deep classification networks. Our Retinal Auto Detection (RADNet) model has been successfully tested on Rotterdam EyePACS AIROGS train dataset with AUC of 0.92, and then additionally finetuned and tested on a fraction of RIM-ONE DL dataset with AUC of 0.91.
