As the use of camera traps in wildlife management in Australia rapidly increases, government agencies, private enterprises, universities and individuals are investing considerable amounts ofmoney in camera trap technology for research, monitoring and recreation. Often camera traps need to be placed along vehicle tracks or in obvious locations to detect animal activity. Consequently, units are f...

Manually following a moving object through a cluttered virtual environment can be challenging for the user. Instead, one would typically rather focus on watching the object and its environment. In this paper, we present an approach to automatically generate a camera motion, such that the user maintains visibility with an object moving along a known path through a virtual environment. To begin, ...

The working region of a camera providing visual feedback to guide manipulation tasks can be greatly extended if the camera can move in real-time. Proper camera motion depends on several different criteria, such as object motion, maximum manipulator tracking speed, manipulator configuration, camera depth-of-field, field-of-view, spatial resolution, occlusion avoidance, etc. In this paper, the co...

A complete framework for automatic calibration of camera systems with an arbitrary number of image sensors is presented. This new approach is superior to other methods in that it obtains both the internal and external parameters of camera systems with arbitrary resolutions, focal lengths, pixel sizes, positions and orientations from calibration rigs printed on paper. The only requirement on the...

Players perceive information about game environments through a virtual camera. While a significant discussion in the industry and in academic research circles has centered around effective camera control, it is focused mainly on occlusion free placement and smooth movement. The relationship between information communicated by the camera about game state and the selection of camera parameters ha...

Good camera control and planning techniques in 3D computer games can give players deeper feelings about atmosphere of games. However, most modern computer games use fixed point-of-view techniques to control the scene camera. We believe applications of some basic cinematic camera planning methods in computer games will enrich player’s gaming experience. In this paper, we discuss the principles o...

The paper studies the optimal placement of multiple cameras and the selection of the best subset of cameras for single target localization in the framework of sensor networks. The cameras are assumed to be aimed horizontally around a room. To conserve both computation and communication energy, each camera reduces its image to a binary “scan-line” by performing simple background subtraction foll...
