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.

Here is a brief example of Effects of bezels in tiled LCD panel displays
