TEM Analysis Pipeline

Overview

This repository contains a pipeline for the analysis of mitochondria morphology using semantic segmentation on Transmission Electron Microscopy (TEM) images. The pipeline includes tools for preprocessing TEM images, training U-Net models for semantic segmentation, generating predictions on new images, and analyzing organelle morphology.
