Nearest feature space (NFS) classifier had been proposed to enhance the limited prototypes’ representation capacity. In this paper, we provide a formal definition and a theoretical analysis to Feature Space. Furthermore, a novel NFS classifier is proposed for face recognition. Experimental results using the ORL face database indicate that the proposed NFS obtains a better recognition performanc...

The results are non-trivial for the real line R, but are formulated for the d−dimensional Euclidean space R, viewed as a prototype for a locally compact Abelian group (with the usual addition of vectors and the topology provided by the Euclidian metric). 1 We start with the description of Mb(G), the space of bounded linear measures, as the dual space of C0, which is naturally endowed with a con...

A high speed 3D reconstruction method using multiple video cameras is presented. The video cameras are set to surround the real 3D space where people exist. Reconstructed 3D space is displayed in voxel format and a user can see the space from any viewpoint with a VR viewer. We implemented a prototype system that can work out the 3D reconstruction with the speed of 7.2 fps in 560ms delay.

Face attractiveness relates positively to the mathematical averageness of a face, but how close attractive faces of varying groups are to their own and to other-group prototypes in the face space remains unclear. In two studies, we modeled the locations of attractive and unattractive Caucasian, Asian, and African faces in participants' face space using multidimensional scaling analysis. In all ...

The objective of this study is to develop “Virtual Collaborator” as a new type of human-machine interface, which works as “intelligent interface agent” to help machine operators manipulating large scale machine system such as power plants. The Virtual Collaborator is a sort of “virtual robot” which behaves as if an intelligent agent robot in virtual reality space, who can communicate naturally ...

The low tidal volume and flow in preschool children may reduce the efficiency of aerosol delivery from a pressurized metered-dose inhaler (pMDI) through a traditional holding chamber. A prototype small-volume steel holding chamber with two one-way valves was devised to prolong aerosol availability in the chamber and to ensure unidirectional airflow. Dead space between the valves was minimized t...
