ABSTRACT
Todays most compelling virtual reality experiences shift the users viewpoint within the virtual environment based on input from a head-tracking system, giving a compelling sense of motion parallax. While this is straightforward for computer generated scenes, photographic VR content generally does not provide motion parallax in response to head motion. Even 360° stereo panoramas, which offer separated left and right views, fail to allow the vantage point to change in response to head motion.

Image-based pan-tilt camera control in a multi-camera surveillance environment
ICME '03: Proceedings of the 2003 International Conference on Multimedia and Expo - Volume 2In automated surveillance systems with multiple cameras, the system must be able to position the cameras accurately. Each camera must be able to pan-tilt such that an object detected in the scene is in a vantage position in the camera's image plane and ...
Pan-tilt-zoom camera calibration and high-resolution mosaic generation
Special issue on omnidirectional vision and camera networksIn this paper, we discuss the problem of estimating parameters of a calibration model for active pan-tilt-zoom cameras. The variation of the intrinsic parameters of each camera over its full range of zoom settings is estimated through a two step ...
GPS-based visual tracking for Pan/Tilt/Zoom camera in a ubiquitous camera environment
The installation of cameras is becoming evermore pervasive, especially in urban areas. In response to this Ubiquitous Camera (UbiCam) environment, a new service, called GPS-based Visual Tracking (GPS-VT), incorporating the Global Positioning System (GPS)...
