Overview

There continues to be growing interest in systems that combine projection technology with computer vision. Examples include automatically calibrated display walls, interactive display surfaces, intelligent environments and performance art. A characteristic of these systems is their ability to passively sense an environment in support of real-time control of projected light. Research in this area spans a number of disciplines including computer vision, computer graphics, HCI and display technologies. In particular, the theory and techniques used by researchers in the area are related, sometimes complementarily, to traditional computer vision techniques employed in stereo-camera and gesture recognition systems. The goal of this workshop is to bring researchers from these different areas together and continue fostering a common research community by examining common research problems and open issues.

The IEEE International Workshop on Projector-Camera Systems (ProCams) series explores systems that combine projection technology with computer vision. ProCams 2003 was collocated with ICCV in Nice, ProCams 2005 was held with the IEEE Conference on Computer Vision and Pattern Recognition (CVPR) in San Diego, and ProCams 2006 was held with CVPR in New York.

The 4th workshop is held in conjunction with CVPR on Monday, June 18, 2007, in Minneapolis, MN. It consists of ten high-quality technical papers organized into sessions on calibration and measurement, real-time applications, and image quality improvements. The workshop also includes ten outstanding posters and three exciting demo presentations to further stimulate for in-depth discussions and on-hands experiences. Finally, we are extremely honored to have Paul Debevec (University of Southern California) and Christopher Jaynes (University of Kentucky) give the keynote and capstone talks, respectively.

In addition to the program committee and the reviewers, we would like to thank in particular our posters chair (Ruigang Yang, University of Kentucky, USA), our demo chair Rahul Sukthankar (Intel Research and Carnegie Mellon University, USA), our online activities chairs (Mark Ashdown, Massachusetts Institute of Technology, USA and Adrian Ilie, University of North Carolina at Chapel Hill, USA), as well as the co-sponsors of ProCams 2007 (Hewlett-Packard, Vioso, and the INI-GraphicsNet Foundation). They all helped to make this workshop a success again.

Best Paper

The Procams 2007 Best Paper Award goes to Niranjan Damera-Venkata and Nelson L. Chang, for Realizing Super-Resolution with Superimposed Projection.

The honorable mention goes to Tyler Johnson and Henry Fuchs, for Real-Time Projector Tracking on Complex Geometry Using Ordinary Imagery.
