Calibration of Video Cameras Using Spheres

Networked video surveillance using multiple omnidirectional cameras

Remote surveillance is widely utilized at bank, shop, office, home and so on. In most conventional remote surveillance systems, fixed or active cameras with a narrow field of view are generally used in order to acquire an image of the remote site. This paper proposes new networked surveillance systems. The proposed surveillance system, which uses multiple omnidirectional cameras and network, is...

Player Viewpoint Video Synthesis Using Multiple Cameras

In this paper, we propose a new method for synthesizing player viewpoint images from multiple view videos in tennis. Our method is divided into two key techniques: virtual-view synthesis and player’s viewpoint estimation. In the former, we divide the object tennis scene into sub regions, which are background, tennis court ground, players, and ball. For each sub region, a virtual viewpoint image...
