The Volume Graphics Research Group

Raghu Machiraju

Research Activities:

His research and technical publications deal with volume rendering, imaging and parallel rendering. Specifically, he is interested in examining issues of accuracy and adaptivity in volume rendering and imaging. Techniques from both classical interpolation and sampling theory and the more recent wavelet theory have been used towards this end. Ongoing work includes wavelet based volume rendering techniques and image comparison metrics. His other research interests include biomedical imaging and high performance computing.
