Features

Glaucoma image detection based on convolutional neural networks.

This repository has the structure:

  • Processor.py - Class that implements some image filter signal processing techniques.

  • Interpreter.py - Class that implements data augmentation procediment and CNN processing based on traditional approach and window optimization technique.

  • test_processor.py - Implements unit tests related to Processor.py class methods.

  • test_processor.py - implements training proccess.

  • Graphs.py - Class that implements graphs visualization.

  • train_model.ipynb - Notebook responsible to train simplified model and and Resnet-20 at AWS-Sagemaker.

  • train_transf_net.ipynb - Notebook responsible to train EfficientNet-B0 until EfficientNet-B7 at AWS-Sagemaker.

Besides of that, into the folder AWS_EvalTest_Results you can find some approaches to automatization of experiments related to tunning hyperparameters.
