Signal processing experimets with glaucoma eye images

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.
