Camera pose estimation under dynamic intrinsic parameter change for augmented reality, Computers & Graphics, This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the(More)
The development of wireless technologies, such as 3G and Wi-Fi, and the rapid growth of mobile devices equipped with sensors have enabled the practical use of Mobile Participatory Sensing (MPS). By gathering and utilizing sensor data using mobile devices, the deployment cost of services can be reduced. In the context of MPS, it is important to establish a(More)
In general, video see-through based augmented reality (AR) cannot change the magnification of camera zooming parameter due to the difficulty of dealing with changes in intrinsic camera parameters. To realize the usage of camera zooming in AR, we propose a novel simultaneous intrinsic and extrinsic camera parameter estimation method based on an energy(More)
The need to keep an attacker oblivious of an attack mitigation effort is a very important component of a defense against denial of services (DoS) and distributed denial of services (DDoS) attacks because it helps to dissuade attackers from changing their attack patterns. Conceptually, DDoS mitigation can be achieved by two components. The first is a decoy(More)
