Methods for Exploiting High Resolution Imagery for Deep Learning Based Diabetic Retinopathy Detection and Grading
Diabetic retinopathy is a disease that affects the eyes of people with diabetes, and it can cause blindness. To diagnose diabetic retinopathy, ophthalmologists image the back surface of the inside of the eye, a process referred to as fundus photography. Ophthalmologists must then diagnose and grade the severity of diabetic retinopathy by analyzing details in the image, which can be difficult and time-consuming. Alternatively, due to the availability of labeled datasets containing fundus images with diabetic retinopathy, AI methods like deep learning can provide automated detection and grading algorithms. These deep learning algorithms sometimes use images at a much lower resolution than is available from fundus photography. However, we show that the resolution of a image has a large effect on the accuracy of the algorithm. Here, we study several techniques to increase the accuracy of the algorithm by taking advantage of higher-resolution data, including increasing the network input size, introducing a region-of-interest channel, and using a non-uniform downsampling approach.
