%K deep learning, glomerular crescent, nephropathology.
%X Glomeruli are structures in the kidneys, responsible for filtering the blood, that can be affected by several lesions, such as the glomerular crescent, which is characterized by abnormal cell proliferation. In this work, different models and conditions for the application of deep learning are to evaluated in the task of classifying glomerular crescent histopathological images. The pre-trained networks Xception, InceptionV3, MobileNet, VGG16 and ResNet50 were compared, by applying to the classification of images with crescent vs normal glomeruli. Comparing the accuracy, precision, recall and f1-score of the models, the ResNet50 showed significantly better performance than the other networks, in all measures. The application of data augmentation did not result in a significant improvement in the results in this case. In an experiment of classification of crescent vs non-crescent glomeruli, adding images of three other lesions to the database, the application of Focal Loss presented greater accuracy and precision.
