In this project we developed a deep learning system applied to human retina images for medical diagnostic decision support. The retina images were provided by EyePACS. These images were used in a Kaggle contest, whose purpose was identifying diabetic retinopathy signs through an automatic detection system. Using as inspiration one of the solutions proposed in the contest, we implemented a model to detect diabetic retinopathy from input retinal images. A preprocessing was applied to the images and then, they were used as input to a deep convolutional neural network (CNN). The CNN performed a feature extraction process followed by a classification stage, which allowed the system to differentiate between healthy and sick patients (using five categories). Finally, we created a system capable of identifying this pathology with an agreement rate with respect to the medical expert’s labels of 76,73% for test data.
