Research
I do research and teach in the areas of computer science, in
particular in the area of visualization,
computer graphics and computer vision.
My research focuses primarily on the following two aspects.
Building large area
high resolution multi-projector displays of high quality: This is a popular
cutting edge technology that has immense applications in the field of
scientific visualization, virtual reality, human computer interaction and
entertainment. The research in this area spans several traditional areas in
computer science including computer vision, computer graphics, image
processing, human-computer interaction and visualization tools. This also
requires a strong background in discrete mathematics. Currently I am working on making such
displays inexpensive, flexible and commonplace by making them both perceptually
and functionally seamless.
Image/Video
processing: Image/video processing is tremendous in today’s world
where everyday we see different kinds of media and need to
process/import/export them in different ways. I am interested in several such
problems, especially in two directions. First, how to preserve geometric and
color property like resolution, sharpness, hue and contrast in the face of
different kinds of image processing. Second, I am also interested in mining
important aspects of the huge amount of image/video data that we have around
today.
