3D Volume Renderization and Connected Component Filtering through Maxtree

André Luís da Costa

Abstract

This page reports the results of a project for 3D MRI data volume visualization using the ray--casting technique implemented in the GPU. The project includes the filtering of connected components organized in a tree structure known as Maxtree. The project was developed over the course IA369E given during the second half of 2013 in the School of Electrical and Computer Engineering, University of Campinas. The produced prototype allow the user to interact with the visualization, to specify custom transfer functions and to filter the data volume. Such functionalities combined give the user the power to enhance and highlight features of interest in the volume being visualized. From learning perspective the results were more than satisfactory, given the knowledge obtained by the student, who is now able to improve and extend the application that can be used in future researches related to the human brain.
