Abstract

As the size and complexity of our data continue to grow at an exponential rate, the need for visual interfaces to see, understand, and manipulate it in the same scale and complexity is becoming evident. Hence, immersive high-resolution displays, usually made of multiple projectors to provide a seamless visual experience, are becoming an essential part of many visualization and virtual reality (VR) systems. These displays come in different shapes and scales like small personalized displays, as are used in gaming consoles or training and simulation systems, to large multi-user installations as are used in large data visualization environments, planetariums, and theme parks. However, building such displays to provide a seamless visualization experience entails several difficult challenges. The talk will present the state of the art techniques, developed as part of my thesis, that have significantly pushed the frontiers of research in automatic calibration of non-planar multi-projector displays.

Speaker Biography

Behzad Sajadi is a Ph.D. candidate at the Department of Computer Science in University of California, Irvine, graduating in summer 2012. He has received his bachelor?s degree from Sharif University of Technology in Iran in 2006. His main research areas are Computer Graphics and Vision with particular interest in multi-projector displays and computational projectors and cameras. He has published several works on geometric and photometric registration of multi-projector displays with the focus of practical designs for commodity large area displays. More recently, he has started working on novel multi-modal camera and display designs with the goal of flexible allocation of resources for better resource utilization. His work at UCI has resulted in 18 top quality publications in premier graphics, visualization, and vision venues including 5 IEEE Transactions on Visualization and Computer Graphics, 3 ACM Transaction of Graphics, 3 Computer Graphics Forum, and 1 European Conference on Computer Vision publications. He has also won two best paper awards including the Best Paper award in IEEE Virtual Reality (VR) 2010 and the Second Best Paper award in IEEE Visualization 2009. He has been collaborating with MIT Media Labs, Canon, Walt Disney Imagineering, and Purdue University on several high impact projects. He has two patents granted and seven more patents pending from his research endeavors pursued at UCI and Canon.
