In this paper, a new teleconference system by using Gigabit Ethernet based omni-directional camera system and flexible middleware system in realtime and bi-directional video transmission is introduced. The omni-directional image has more advantages than conventional one-directional camera in that it provides a wider view than a single directional camera and able to realize flexible teleconferen...

Omni-directional mobile robots have been popularly employed in several application areas. However, the kinematics for these systems have not been clearly identified, specially for redundantly actuated case which is common in omni-directional mobile robot such as Nomadic model. For such mobile robot systems, exploitation of redundant actuation as well as singularity analysis has not been extensi...

Omni-optimization assumes a capability to perform any type of optimization, e.g. singleand multi-objective, using single optimization algorithm, or the omni-optimizer. This paper addresses a novel concept for omni-optimization, by coupling vectorization with genetic algorithms (GAs). Vectorization assumes converting constraints into objectives, and their optimization alongside the original set ...

Many applications are facing the problem of learning from an objective dataset, whereas information from other auxiliary sources may be beneficial but cannot be integrated into the objective dataset for learning. In this paper, we propose an omni-view learning approach to enable learning from multiple data collections. The theme is to organize heterogeneous data sources into a unified table wit...

Emerging technologies enable customers to define by themselves through which channels they would like to interact with retailers. These technologies also enable retailers to emancipate from traditional channels, to offer services anytime and anywhere, and eventually to evolve into omni-channel retailers. In fact, most interactions between customers and retailers are enabled by information techn...

This research aims to obtain 3D information by using spatio-temporal analysis of omni images for outdoor navigation and map-making in the intelligent transportation system (ITS) application. Two types of omnidirectional cameras are employed to make a spatio-temporal volume, which is a sequence of omni images stacked in the spatio-temporal space. For the spatio-temporal analysis of an omni image...

The EC project OMNI ("Open Model For Network-wide Heterogeneous Intersection-based Transport Management") [1] provides an open-architecture model for road traffic management, by defining: standard interfacing for new applications or devices, and the integration of technology (surveillance applications, advanced sensors, other urban traffic strategies, etc) from different vendors. One of the dev...

In this paper, we propose a framework for modelling agent organizations, Omni, that allows the balance of global organizational requirements with the autonomy of individual agents. It specifies global goals of the system independently from those of the specific agents that populate the system. Both the norms that regulate interaction between agents, as well as the contextual meaning of those in...

The use of wireless sensor networks to protect sensitive facilities or international borders has attracted more and more attention. In contrast to previous studies in which the barrier coverage problem was solved under the assumption of an omni-directional sensing model, the current study presents a scheme for constructing k-barrier coverage using randomly deployed sensors with directional sens...
