ADITI MAJUMDER: A Practical Framework to Achieve Perceptually Seamless Multi-Projector Displays (Under the direction of Prof. Greg Welch and Prof. Rick Stevens) Arguably the most vexing problem remaining for planar multi-projector displays is that of color seamlessness between and within projectors. While researchers have explored approaches that strive for strict color uniformity, this goal ty...

With the recent advancements in digital technology, three-dimensional (3-D) shape measurement has played an increasingly important role in fields including manufacturing, homeland security, medical sciences, and entertainment. Over the past decades, numerous 3D shape measurement techniques have been developed. Among these existing techniques, fringe analysis based on phase-shifting sinusoidal s...

Many applications that use three-dimensional scanning require a low cost, accurate and fast solution. This paper presents a fixed-point implementation of a real time active stereo threedimensional acquisition system on a Texas Instruments DM6446 EVM board which meets these requirements. A time-multiplexed structured light reconstruction technique is described and a fixed point algorithm for its...

The idea of designing a new map projection via combination of two projections is well established. Some of the most popular world map projections in use today were devised in this manner. One construction method is to combine two source projections along a common parallel (for example, Goode’s homolosine combines the sinusoidal and the Mollweide projections). A second method calculates the arit...
