3D-Convolutional-Neural-Network-for-Medical-Image-Segmentation

This project was developed for the Neural Networks exam, academic year 2021/2022, University La Sapienza of Rome.

Getting Started

The goal of the first task of this project is to modify the classical U-shaped architecture of the convolutional neural network for MRI (U-Net). In the second task was provided a TensorFlow implementation of my network to work with a breast cancer dataset (BUSI).

First task

The dataset used for this task is IXI Tiny. The original IXI dataset is a collection of 600 MR brain images from normal, healthy subjects. The architecture consists of a contracting path to capture context and a symmetric expanding path that enables precise localization.
In the upsampling part we have also a large number of feature channels, which allow the network to propagate context information to higher resolution layers.

Second task

The dataset used for this task is BUSI. Is possible to see how the network implemented for the first tisk is able to achieve really good results also for the segmentation of breast cancer images.

Installing

In this repository there are 2 Colab Notebooks. All the code can be runned using Google Drive on every browser.
You have simply to paste all the Notebooks in your Drive.
