Medical Imaging

Most of my undergraduate research experience was in content-based image retrieval (CBIR) systems for medical images, and particularly for computed tomography (CT) images of lung nodules. During the summer of 2006, I participated in the MedIX research experience for undergraduates (REU) program at DePaul University in Chicago.

BRISC Overview

I was on a team with two other undergraduate computer science students under the leadership of Dr. Daniela Raicu. We developed an image lookup tool for the database of lung nodule images provided by the Lung Image Database Consortium (LIDC). With this tool we compared the retrieval effectiveness of three different texture features extraction methods: Haralick co-occurrence matrices, Gabor filtering, and Markov Random Fields. I presented our results at the SPIE Medical Imaging ’07 conference in San Diego.

We were able to release the project source code under the GNU General Public License (GPL) and it is available on SourceForge. The figure above shows an overview of what the tool does. For more information, you can check out our documentation and papers on the website.
