I enjoy working with my students. The poet wrote: "I am a part of all that I have met." I have always wanted to achieve that. Yet in many ways my students are a greater part of me than they probably realize. While compiling this list, I noted how much I learnt from them and how some of the exploratory (and, often, grunt) work done by earlier students developed later to others' work. Their work reflected my interests as the years went by.
Woraphon "Mae" Watunyuta (M.S. 1990, Ph.D. 1994) Mae's M.S. thesis was on contour shape matching using a constraint satisfaction network. After working for a year in the industry, he returned to pursue his Ph.D. He developed a human visual system-based halftoning algorithm and a Voronoi-based spatial domain metric for halftones. His inverse halftoning method was based on a graduated nonconvex surface reconstruction algorithm. May's M.S. (computer engineering) and Ph.D. (computer engineering) theses were the first in their categories supervised by me. After he graduated, May returned home to Thailand. In 1998, he joined K-Computing, San Jose, Calif., as a member of the technical staff.Naresh Miglani (M.S. 1992) Naresh's M.S. thesis was on three-dimensional shape representation by quadratic surfaces and superquadric volumes. Through his work, we learnt volume fitting and nonlinear minimization using the Levenberg-Marquardt method. Mr. Miglani now owns and operates a software development company in south Florida.Jaganmohan Yeccaluri (M.S. 1992) Jagan worked on multirate image processing and the design of halfband filters. In additional to his thesis work, he did some exploratory work in wavelet analysis. Mr. Yeccaluri joined Intel in Portland, Ore., after his graduation.Chi-Kei Rick Chow (Ph.D. 1994) Rick was my first computer science Ph.D. student. He developed a genetic algorithm-based method for evolving the architecture of an artificial neural network. Dr. Chow is now an associate professor of computer science at the University of South Carolina-Spartanburg.Boriboon Patwiwat (Ph.D. 1995) Boriboon worked on metrics for measurement accuracy of image velocity in the frequency domain. He also implemented and measured the compression rates of EEG data sets using the embedded zerotree coding of wavelet coefficients. Dr. Patwiwat returned to his home country of Thailand after graduation.Sri-Krishna Aditya (Ph.D. 1996) Krishna was interested in the wavelet transform and we learnt much about the wavelet transform together. In his dissertation work, he developed architectures for the wavelet transform and methods for customizing a mother wavelet. The latter was applied to ECG data processing, a topic I first explored while a graduate student. Dr. Aditya is now an associate professor at Alcorn State University, Lorman, Miss.Jui-kun (Jack) Chen (Ph.D. 1996) Jack's work was on image and video compression. He developed a hierarchical, vector quantized block truncation code for images. We figured out the basic issues of video compression when he applied his method to compress motion compensation errors. Jack also started my interest in attending the Siggraph conference. Dr. Chen is now a senior member of technical staff at Thompson Consumer Electronics, Indianapolis.Daryoush Razi (M.S. 1991, Ph.D. 1997) Daryoush started working with me on using nonlinear filters for multiresolution processing of ultrasound signals as an extension of his digital signal processing course project. The work was subsequently developed into his M.S. thesis. For his dissertation, Daryoush showed how the alpha-trimmed-mean filter can be realized on the threshold decomposition architecture, and how nonlinear filters are effective for 3d mipmapping in volume visualization. While studying for his Ph.D. degree, Daryoush worked at the NASA Stennis Space Center, Miss. Dr. Razi is currently with Kodak's Professional Motion Imaging Group in Rochester, N.Y.Nancy Breaux (Ph.D. 1998) Nancy developed a multiresolution color halftoning algorithm that uses an arbitrary palette. Her results showed neither color shifts nor color spikes, which often plaqued the only other color halftoning algorithm for an arbitrary palette. Dr. Breaux is currently with the Naval Surface Warfare Center, Dahlgren, Va.Hao Duan (Ph.D. 1998) Hao's interest was in video compression. He developed wavelet-based wrappers for the H.263 low bit rate codec. Dr. Duan joined Sharp Microelectronics' Digital Information Products group in Huntington, Calif., following his graduation. His company recently filed a patent for his work in H.263 rate control.Marie Erie (Ph.D. 1999) Marie's interests were in graphics and visualization and in cognitive and biomedical sciences. Her dissertation work was on the fusion of EEG and MRI data, resulting in a visualization pipeline that combined the temporal resolution of EEG with the spatial resolution of MRI data. She validated her results using visual evoked potential and epileptic data sets. Marie is the first graduate of mine to have a home page. Dr. Erie is currently with the Mitre Corp., McLean, Va.
Human beings like to belong to groups. Exploiting this human nature, bureaucrats like to organize workers into unambiguous units. I work for the State of Louisiana. Here's the hierarchy:State Government > University of Louisiana system > The University of LouisianaWithin CACS, I and my students work in the Laboratory for Internet Computing (LINC). Our group is unofficially called the Media Technology group because our lab (prior to joining LINC) was the Media Technology (MT) Laboratory.
> College of Sciences > Center for Advanced Computer Studies (CACS).
Our laboratory is part of an innovative Louisiana Board of Regents project entitled Joint Faculty Appointments Program (JFAP). With strong support from the National Science Foundation, JFAP has been hailed as having the potential to become a model program for the nation. Click here for further information.
