Research Seeks to Refine Data Transmission for Medical Diagnoses
Dr. Xiaohu Guo knew the research expectations for faculty in the computer science department at UT Dallas were high, but he didn’t know his work this semester would be boosted by a $448,000 National Science Foundation CAREER (Faculty Early Career Development) award. Guo, an associate professor in the Erik Jonsson School of Engineering and Computer Science, is researching the theoretical foundations of a certain type of spectral transformations for 3-D models and is developing techniques to enable more efficient transmission of 3- and 4-D models via the Internet. If these models could be communicated in real time, doctors in different locations could more easily work collaboratively to diagnose and treat diseases. Guo has had success transforming large amounts of scanned data using what is known as spectral transformation techniques. Those techniques rely on manifold harmonics to first transform the model into frequencies and then compress the data into a smaller form that can be sent faster over networks. Guo is the ninth CAREER Award holder in the computer science department. Other recipients include Drs. Kevin Hamlen, Sanda Harabagiu, Murat Kantarcioglu and Yang Liu, all associate professors; and Drs. Jason Jue, Ravi Prakash, Balakrishnan Prabhakaran and Edwin Sha, all professors.
3-D Imaging Technique Utilizes Famous Mathematician's Theory
UT Dallas computer scientists have developed a technique to make 3-D images that finds practical applications of a theory created by a famous mathematician.

This technique uses anisotropic triangles – triangles with sides that vary in length depending on their direction – to create 3-D “mesh” computer graphics that more accurately approximate the shapes of the original objects, and in a shorter amount of time than current techniques. These types of images are used in movies, video games and computer modeling of various phenomena, such as the flow of water or air across the Earth, the deformation and wrinkles of clothes on the human body, or in mechanical and other types of engineering designs. Researchers hope this technique will also lead to greater accuracy in models of human organs to more effectively treat human diseases, such as cancer
