This repository contains the MATLAB scripts and analyses developed as part of my undergraduate thesis in Biomedical Engineering at the Federal University of Uberlândia (UFU). The thesis focuses on evaluating active contour segmentation methods and the influence of preprocessing techniques in mammographic image analysis.
📄 Access the thesis: Evaluation of Active Contour and the Influence of Preprocessing in Breast Nodule Segmentation
-
Processing.m: Implements the preprocessing techniques and segmentation methods. This includes Wiener filtering, wavelet denoising, CLAHE, and active contour segmentation using the Level-Set sparse field method.
-
Metrics.m: Contains the functions for calculating and evaluating key metrics such as eccentricity, Hausdorff distance, and segmented area. This file is used to assess the performance of the segmentation results.
